1997 SA-1 (STAG1) was identified as a novel nuclear protein of ~120 kDa expressed in hematopoietic organs, cloned from mouse stromal cell and human thymus cDNA libraries. A closely related paralog SA-2 was also cloned, sharing 71% identity. Subcellular fractionation demonstrated nuclear localization of SA-1 protein.

2009 Cohesin-SA1 and cohesin-SA2 have distinct, non-redundant roles in sister chromatid cohesion: SA1 is specifically required for telomere cohesion after DNA replication in S phase, while SA2 is required for centromere cohesion. Depletion of SA1 but not SA2 caused loss of sister telomere cohesion, inability to repair chromatid breaks, and sister telomere loss. The telomere cohesion function of SA1 was shown to be linked to the telomeric protein TIN2. siRNA depletion of SA1 or SA2 in human cells, fluorescence in situ hybridization (FISH) for telomere/centromere cohesion, live-cell imaging, cell cycle analysis The Journal of cell biology High 19822671
2012 SA1 is largely responsible for cohesin accumulation at gene promoters and CTCF-bound sites genome-wide. SA1 ablation alters transcription of genes related to Cornelia de Lange syndrome, and cohesin-SA1 positively regulates expression of myc and protocadherin genes at their promoters — a function that cannot be compensated by cohesin-SA2. ChIP-seq in wild-type and SA1-null mouse embryonic fibroblasts, RNA-seq, SA1-null mouse embryo generation The EMBO journal High 22415368
2012 Complete SA1 ablation in mice causes embryonic lethality; heterozygous SA1-deficient animals show shorter lifespan and earlier tumor onset. SA1-null MEFs display increased aneuploidy and chromosome segregation defects arising specifically from defective telomere replication, not from impaired centromeric cohesion (which depends on cohesin-SA2). SA1 is thus specifically required for telomere replication-associated cohesion. SA1-null mouse model generation, MEF culture, cytogenetic analysis, BrdU incorporation, metaphase spreads, telomere FISH The EMBO journal High 22415365
2013 SA1 binds directly to telomeric DNA through a unique AT-hook motif in its N-terminal domain (absent in SA2). Overexpression of SA1 alone is sufficient to induce cohesion at telomeres independently of the cohesin ring, and this requires the AT-hook-containing N-terminal domain. SA1 is highly enriched at telomeres by ChIP, decreases at mitosis when cohesion is resolved, and increases when cohesion persists. ChIP in human cells, overexpression of SA1 truncation mutants, AT-hook mutation analysis, telomere cohesion assays by FISH Journal of cell science High 23729739
2013 SA1 and SA2 interact with RAD21 (Rad21/Scc1) through two distinct SA-binding motifs on RAD21: an N-terminal motif (aa 60-81) and a middle-part α-helical motif (aa 383-392). Mutation of three conserved residues (L385, F389, T390) in the α-helical motif significantly disrupts Rad21-SA1/2 interaction without affecting Smc1-Smc3-Rad21 interaction. Mutant Rad21 fails to rescue precocious chromosome separation caused by endogenous Rad21 depletion.

2013 Cohesin-SA2 (not SA1) is the main complex co-recruited with the cohesin-loading factor NIPBL to DNA damage sites in an S/G2-phase-specific manner. Replacing the diverged C-terminal region of SA1 with the corresponding region of SA2 confers DNA damage site accumulation activity on SA1. SA2 depletion (not SA1) decreased sister chromatid homologous recombination repair and affected DNA repair pathway choice. Both cohesin complexes function in the intra-S checkpoint.

2016 SA1 displays two-state DNA binding behavior: non-specific 1D free diffusion for DNA searching, and subdiffusive sliding at telomeric regions for recognition. The AT-hook motif in SA1 modulates both non-specific DNA binding and subdiffusive dynamics over telomeric sequences. TRF1 tethers SA1 within telomeric regions, and together SA1 and TRF1 form longer DNA-DNA pairing tracts than TRF1 alone.

2017 STAG1 and STAG2 display a strong synthetic lethal interaction: STAG1 loss abrogates sister chromatid cohesion specifically in STAG2-mutated cells (not wild-type), leading to mitotic catastrophe, defective cell division, and apoptosis. Restoration of STAG2 expression alleviates dependence on STAG1. This synthetic lethality was demonstrated across bladder cancer and Ewing sarcoma cell lines.

2018 Cohesin-SA1 and cohesin-SA2 have distinct genomic distributions and non-redundant contributions to 3D genome organization: cohesin-SA1 preferentially stabilizes topologically associating domain (TAD) boundaries together with CTCF, while cohesin-SA2 promotes cell-type-specific enhancer-promoter contacts independently of CTCF. Loss of SA2 rewires local chromatin contacts in a way that cannot be compensated by SA1.

2019 Stag1 and Stag2 bind a shared set of genomic loci in hematopoietic stem and progenitor cells, but a component of Stag2 binding sites is unoccupied by Stag1. Stag2 loss decreased chromatin accessibility and transcription of lineage-specification genes (Ebf1, Pax5), increasing self-renewal and reducing B cell commitment. Concurrent loss of both Stag1 and Stag2 abrogated hematopoiesis entirely, demonstrating partial redundancy.

2019 In mouse embryonic stem cells, cohesin-SA1 disrupts Polycomb domain interaction networks and preserves TAD borders, whereas cohesin-SA2 facilitates Polycomb domain compaction through PRC1 recruitment and promotes long-range interactions between Polycomb-bound promoters. These two modes of action reflect distinct roles: SA1 in loop extrusion with CTCF for TAD organization, SA2 in local transcriptional hub organization.

2020 ESCO1 acetyltransferase and CTCF protect a subset of cohesin-STAG1 complexes from removal by WAPL, enabling formation of long chromatin loops. During G1 phase, acetylated cohesin-STAG1 binds chromatin for hours while cohesin-STAG2 binds for minutes. ESCO1 and CTCF together contribute to boundary formation in chromatin looping, consistent with a nested loop extrusion model where stable cohesin-STAG1 loops demarcate boundaries for more transient cohesin-STAG2 extrusion.

2020 Cohesin SA1 and SA2 are direct RNA-binding proteins. Both bind ssRNA, dsRNA, RNA:DNA hybrids, and R-loops in vitro, and localize to RNA-containing regions on dsDNA in single-molecule experiments. SA1 and SA2 binding sites overlap significantly with R-loop (DRIP-seq) sites in cells, with most R-loop-localized SA1/SA2 also binding other cohesin subunits.

2020 STAG1 was identified as the most prominent and selective genetic dependency of STAG2-deficient cells in genome-wide CRISPR screens. X-ray crystallography identified the STAG1 regions that interact with RAD21. STAG1 mutations that abrogate interaction with RAD21 selectively compromise viability of STAG2-deficient cells. Chemical-genetic degradation of STAG1 using an inducible degron causes loss of sister chromatid cohesion and rapid cell death specifically in STAG2-deficient cells.

2012 Nuclear import of human SA1/STAG1 depends on a functional N-terminal NLS. In contrast to SA2 (which has multiple functional NLS and NES signals), SA1 has only one functional NLS, located at its N-terminus, with no functional nuclear export signals identified, suggesting SA1 is constitutively nuclear.

2023 TRF1, TIN2, and SA1 act synergistically to compact telomeric DNA. SA1 alone can compact telomeric DNA, and compaction by the full ternary TRF1-TIN2-SA1 system is additive (TRF1-TIN2 component plus SA1 component). Atomic force microscopy confirmed that all three proteins together drive strong intermolecular aggregation as required for chromosome cohesion.

2023 STAG1 is the dominant paralog in mouse embryonic stem cells and is required for pluripotency. The N-terminus of STAG1 specifically represses the two-cell (2C) embryonic state by maintaining rRNA expression and nucleolar integrity. Skewing the balance of naturally occurring STAG1 isoforms impacts cell identity. This role in nucleolar structure is distinct from STAG1's role in chromatin loop organization. mESC STAG1 depletion, isoform-specific overexpression, RNA-seq for 2C gene markers, rRNA expression analysis, nucleolar morphology by immunofluorescence Stem cell reports Medium 37802073
2024 KPT-6566 was identified as a dual inhibitor of STAG1 and STAG2 that disrupts their interactions with SCC1 and double-stranded DNA. KPT-6566 causes premature chromosome separation, chromosome damage, impaired DNA damage repair, accumulation of double-strand breaks, and cell apoptosis in HeLa cells. It also sensitizes cells to PARP inhibitor Olaparib and NHEJ inhibitor UMI-77.

2025 STAG1 binds tightly to the trimeric SMC1/SMC3/SCC1 complex; this tetramer then weakly but cooperatively binds DNA. NIPBL binds DNA tightly and acts as a DNA anchor during the mechanochemical loop extrusion cycle. An ATP-modulated DNA binding site created by the STAG1-SMC1/SMC3/SCC1 interaction is important for repeated DNA grabbing and release critical to loop extrusion.

2020 Cohesin-STAG1 specifically contributes to stabilization of TAD boundaries together with CTCF, while cohesin-STAG2 promotes cell-type-specific contacts between enhancers and promoters independently of CTCF. These findings establish distinct 3D genome organization roles for the two cohesin variants.

2025 Cohesin-STAG1 extrudes DNA loops more efficiently than cohesin-STAG2 in single-molecule assays, despite comparable ATPase activity and topological DNA entrapment. The AT-hook motif unique to the STAG1 N-terminus promotes loop extrusion without altering ATPase activity or DNA binding. In human somatic cells, the AT-hook is required for stable cohesin-chromatin association during G1 phase (but dispensable for sister chromatid cohesion), and its mutation markedly impairs TAD and chromatin loop formation.

2025 Stag1 depletion has negligible impact on post-mitotic genome restructuring or transcription reactivation during mitosis-to-G1 transition, whereas Stag2 orchestrates early-G1 chromatin remodeling. Simultaneous depletion of both Stag proteins results in synergistic loss of virtually all structural loops and more severe transcriptional disruption than individual deletions, demonstrating that Stag1 provides compensatory support during genome refolding.

2025 The CTCF N-terminal region contains two motifs (YDF and KTYQR) that hinder cohesin-mediated loop extrusion. The KTYQR motif fully impedes loop extrusion activity, while YDF converts cohesin into a unidirectional extruder by strengthening the affinity of STAG1 to DNA, revealing that CTCF stalls loop extrusion partly through modulating STAG1's DNA affinity.

2025 Loss of SA1 (the Drosophila STAG1/2 homolog) during brain development leads to defects in neural stem cell differentiation and promotion of tumorigenesis. PARP inhibition combined with SA1/STAG2 depletion results in apoptosis in vitro and in vivo, and reduction of PARP activity ameliorates tumor-associated phenotypes of SA1-deficient Drosophila tissue, suggesting synthetic lethality between cohesin and PARP activity.
