Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

CENP-C is a conserved inner kinetochore scaffold that bridges centromeric chromatin to the outer kinetochore machinery and is essential for accurate chromosome segregation (PMID:1339310, PMID:9361037, PMID:10428958). It binds the CENP-A nucleosome directly, recognizing a hydrophobic region of the CENP-A tail and docking onto the H2A/H2B acidic patch through both its central region and the conserved CENP-C motif (PMID:23723239, PMID:31475439); this engagement reshapes the nucleosome by rigidifying the histone core and driving lateral DNA gyre sliding toward canonical positioning (PMID:25954010, PMID:26878239). CENP-C also contacts centromeric AT-rich/alpha-satellite DNA through internal DNA-binding/centromere-targeting domains, integrating histone and DNA recognition into contiguous binding modules (PMID:7883764, PMID:12006616, PMID:29074736). From this chromatin platform, the conserved N-terminal motif of CENP-C binds the Mis12 complex with high affinity to nucleate assembly of the full KMN network and outer kinetochore (PMID:19641019, PMID:21353556), while its PEST region recruits the CENP-HIKM subcomplex, establishing CENP-C as a blueprint for assembly of the broader CCAN (PMID:26124289). C-terminal Cupin-domain oligomerization and dimerization organize centromeric chromatin architecture and are required for CCAN localization (PMID:37295434, PMID:40997799). CENP-C additionally sustains the centromeric epigenetic state by recruiting the M18BP1/Mis18 complex to drive new CENP-A loading (PMID:21911481, PMID:22540025) and by recruiting DNMT3B to direct centromeric DNA methylation, with its loss increasing missegregation and centromeric repeat transcription (PMID:19482874). These activities are gated by mitotic kinases: CDK1 phosphorylation of the C-terminal region enhances CENP-A binding, whereas Aurora B phosphorylation of the N-terminal region modulates the Mis12 interaction for error correction, forming a positive regulatory loop that reinforces biorientation (PMID:27881301, PMID:29180432, PMID:31676716, PMID:39433344). Genetic and biochemical conservation from yeast Mif2 through worm, fly, and plant orthologs underlies roles in kinetochore assembly, the spindle assembly checkpoint, and meiotic functions including mono-orientation and PLK-1 recruitment (PMID:7579695, PMID:17392512, PMID:19758558, PMID:37067150).

2017 Yeast Mif2/CENP-C uses a contiguous DNA- and histone-binding domain (DHBD) containing the CENP-C motif, an AT-hook, and RK clusters to contact both Cse4/CENP-A residues and AT-rich centromere DNA simultaneously; human CENP-C has two related DHBDs that preferentially bind higher AT content DNA. Biochemical binding assays, mutational analysis, structural analysis Genes & development High 29074736
2017 Aurora B kinase phosphorylates the N-terminal region (Thr28) of S. pombe CENP-C (Cnp3), impairing its interaction with the Mis12 complex; a phosphomimetic mutant causes defective chromosome segregation due to improper kinetochore assembly. Kinase assay, co-immunoprecipitation, crystal structure of Mis12-Nnf1 complex, mutant expression in S. pombe PNAS High 29180432
2019 CDK1 phosphorylates the C-terminal region of CENP-C (at conserved sites), facilitating its binding to CENP-A nucleosomes in vitro and in vivo; this CENP-A binding promotes CENP-C kinetochore localization during mitosis, and the CENP-A–CENP-C interaction is critical for long-term viability in human RPE-1 cells. In vitro kinase assay (CDK1), Phos-tag SDS-PAGE, co-immunoprecipitation, immunofluorescence in chicken and human cells, cell viability assays The Journal of cell biology High 31676716
2019 Human CENP-C central region (CENP-CCR) and CENP-C motif both bind exclusively to CENP-A nucleosomes in vitro; CENP-CCR binds with high affinity through CENP-AV532 and CENP-AV533 (extended hydrophobic area); CENP-CCR binding destabilizes the H2A C-terminal tail (further exacerbating loose DNA wrapping) and rigidifies H4 N-terminal tail in the conformation favoring H4K20 monomethylation. Cryo-EM structure of CENP-A nucleosome, in vitro binding assays, mutagenesis EMBO reports High 31475439
2020 Mif2/CENP-C exhibits auto-inhibition: wild-type Mif2 is attenuated in binding the Mtw1 complex, and binding Cse4/CENP-A nucleosomes overcomes this inhibition; a Mif2 mutant bypassing Cse4 requirement for Mtw1 binding causes mis-localization of the Mtw1 complex and chromosome segregation defects in vivo. In vitro binding assays with reconstituted nucleosomes, yeast genetics, immunofluorescence The EMBO journal High 32515113
2022 lncRNA CCTT recruits CENP-C to centromeric DNA via RNA-DNA triplex formation and a direct RNA-protein interaction with CENP-C; CCTT loss triggers mitotic errors and aneuploidy, and CCTT localizes to all centromeres. RNA immunoprecipitation, RNA-DNA triplex assay, siRNA/shRNA depletion, immunofluorescence, FISH Molecular cell Medium 36332605
2023 CENP-C undergoes self-oligomerization through its C-terminal Cupin domain (demonstrated by structural and biochemical analyses of chicken and human CENP-C); this oligomerization is vital for CENP-C function, centromeric localization of CCAN proteins, and centromeric chromatin organization. Crystal structure of Cupin domain, biochemical self-oligomerization assays, mutagenesis, immunofluorescence in chicken cells Molecular cell High 37295434
2023 In C. elegans oocytes, CENP-C (HCP-4) directly recruits PLK-1 to the chromosome arm during meiosis (independent of BUB-1); disruption of the CENP-C–PLK-1 interaction leads to imbalance in kinetochore components and chromosome congression defects without affecting CDC-20 recruitment. Live imaging, biochemical interaction assays, RNAi, degron-mediated depletion in C. elegans oocytes eLife High 37067150
2023 Multi-site phosphorylation of the PEST region of yeast Mif2/CENP-C enhances inner kinetochore assembly; eliminating PEST phosphorylation sites progressively impairs cellular fitness and causes lethality in cells lacking otherwise non-essential inner kinetochore factors. Yeast genetics, phosphorylation-site mutagenesis, genetic interaction analysis Current biology Medium 36736323
2024 In C. elegans embryos, CENP-C targets PLK-1 to the inner kinetochore during prometaphase and metaphase; disruption of the CENP-C–PLK-1 interaction causes kinetochore component imbalance and chromosome congression defects distinct from the effects of BUB-1-targeted PLK-1 (which controls CDC-20 recruitment and SAC). Engineered protein interaction mutants, live imaging, immunofluorescence in C. elegans embryos Journal of cell science High 39355896
2024 The CENP-C–Mis12 complex (Mis12C) interaction facilitates centromeric recruitment of Aurora B; Aurora B in turn reinforces the CENP-C–Mis12C interaction, creating a positive regulatory loop that ensures kinetochore biorientation and error correction. Immunofluorescence, co-immunoprecipitation, CENP-C mutant analysis in human RPE-1 cells and mouse models Life science alliance Medium 39433344
2025 Maternal CENP-C is recruited asymmetrically to paternal centromeres in the zygote, and this recruitment is required to equalize CENP-A levels between maternal and paternal centromeres before first mitosis; disruption of CENP-C dimerization impairs CENP-A equalization and chromosome segregation. CENP-A-mScarlet mouse model, live imaging, maternal CENP-C depletion, dimerization-disrupting mutants Developmental cell High 40997799
2025 KIF18A promotes chromosome alignment in cooperation with CENP-E downstream of CENP-C; a genome-wide Cas9 screen using a hypomorphic CENP-C mutant identified KIF18A as synthetic lethal, with the synthetic defect caused by reduction in CENP-E function in the CENP-C mutant background. Genome-wide Cas9 functional genetics screen, synthetic lethality, immunofluorescence Cell reports Medium 41218610
