Synthesis pass · prose summary of the discoveries below

SSNA1 (NA14) is a small coiled-coil protein that self-assembles into fibrillar structures and functions as a microtubule-associated damage sensor, stabilizer, and centriolar scaffold component essential for cytokinesis, cilia assembly, and neuronal morphogenesis. SSNA1 forms anti-parallel coiled-coil fibrils through C-terminal triple-stranded junctions that create microtubule-interaction hubs; it cooperatively binds the microtubule lattice, preferentially accumulates at damage sites, slows catastrophe, promotes rescue, and protects microtubules from spastin-mediated severing (PMID:34970964, PMID:40804232). SSNA1 localizes to the distal lumen of centrioles downstream of C2CD3/SAS-1 in a hierarchical targeting pathway, where it participates in a luminal ring scaffold and is required for CP110 removal during ciliogenesis (PMID:41124206, PMID:25390646). Through its physical interaction with the microtubule-severing ATPase spastin, SSNA1 acts as a spatial adaptor at centrosomes and along neuronal microtubules, and its loss causes multipolar spindles, cytokinesis failure, and impaired axon branching (PMID:15269182, PMID:25390646, PMID:40804232).

1998 NA14 (SSNA1) is a nuclear autoantigen of 14 kDa containing an acidic N-terminal domain (aa 6-80) with heptad repeats characteristic of dimeric coiled-coil alpha-helices, and an alkaline C-terminal domain (aa 81-119). It localizes to numerous punctate structures scattered throughout the nucleus of HeLa and 3T3 cells. cDNA library screening with autoimmune serum, immunoprecipitation, recombinant protein expression, confocal immunofluorescence microscopy of transiently transfected cells The Journal of biological chemistry High 9430706
2003 The Chlamydomonas orthologue DIP13 and human NA14 localize to microtubule structures including basal bodies, flagellar axonemes, and cytoplasmic microtubules; anti-DIP13 antibody cross-reacts with human NA14 at centrosomes and basal bodies of human sperm. Antisense knockdown of DIP13 in Chlamydomonas produces multinucleate, multiflagellate cells, implicating DIP13/NA14 in proper cell division. Antibody generation, immunofluorescence microscopy, antisense knockdown in Chlamydomonas Journal of cell science High 12640030
2004 Spastin physically interacts with the centrosomal protein NA14 (SSNA1), co-fractionates with the centrosomal marker gamma-tubulin, and is enriched at the spindle pole, central spindle, midbody, distal axon, and branching points. Deletion of the spastin region required for NA14 binding disrupts spastin's interaction with microtubules, suggesting NA14 targets spastin activity to the centrosome. Co-immunoprecipitation, subcellular fractionation, immunofluorescence microscopy in dividing cells and immortalized motoneurons, domain deletion analysis Human molecular genetics High 15269182
2008 NA14 binds to the C-terminal region of the orphan receptor TPRA40/GPR175, identified by yeast two-hybrid and confirmed by GST pull-down and co-immunoprecipitation. NA14 mediates functional plasma membrane transport of TPRA40; an N-terminal deletion mutant of NA14 that cannot bind microtubules but retains TPRA40 binding inhibits TPRA40 translocation to the plasma membrane, impairing TPRA40's regulation of cell division in mouse embryos. Yeast two-hybrid screening, GST pull-down, co-immunoprecipitation, live-cell imaging, mouse embryo microinjection Journal of cellular physiology Medium 18459117
2011 Human NA14 forms a parallel coiled-coil structure spanning residues 14-104 that mediates self-association; N- and C-termini lack preferred structure. Leu83 and Leu93 are proposed to mediate interactions among NA14, spastin, and microtubules. NA14 tends to oligomerize and form fibrils in solution.

2012 The Trypanosoma brucei SSNA1 orthologue TbDIP13 self-assembles into fibril-like structures both in vitro and in vivo, partially co-localizes with acetylated alpha-tubulin, and deletion has little effect on parasite growth—suggesting possible functional redundancy. Comparative proteomics identified potential interacting partners. Electron microscopy of fibril structures, immunofluorescence co-localization with acetylated alpha-tubulin, gene deletion, comparative proteomics PloS one Low 22363749
2014 Endogenous NA14 (SSNA1) localizes specifically to centrioles in HeLa cells and rat cortical neurons. Stable NA14 knockdown dramatically impairs cytokinesis. Overexpression of NA14 in neurons significantly increases axon outgrowth, branching, and neuronal differentiation. NA14 is proposed to act as an adaptor regulating spastin localization to centrosomes.

2016 The SSNA1/DIP13 homologue in Toxoplasma gondii localizes to the conoid of the apical complex in mature and dividing cells, and to the basal complex during cell division. The protein self-associates into higher-order structures both in vitro and in vivo, and overexpression impairs parasite division. Immunofluorescence with parasite-specific markers, in vitro self-assembly assays, overexpression phenotypic analysis Scientific reports Medium 27324377
2021 Human SSNA1 directly modulates all parameters of microtubule dynamic instability in vitro: it slows growth, shrinkage, and catastrophe rates, and promotes rescue. SSNA1 forms stretches along growing microtubule ends, binds cooperatively to the lattice, becomes enriched at microtubule damage sites (both naturally occurring and induced by spastin severing), and protects microtubules against spastin-mediated severing. In vitro reconstitution with purified proteins, TIRF microscopy, dynamic instability analysis, spastin severing assays eLife High 34970964
2024 The cryo-EM structure of C. elegans SSNA-1 at 4.55 Å resolution reveals that SSNA1 forms an anti-parallel coiled-coil, with self-assembly driven by 16 C-terminal residue overhangs that dock on adjacent coiled-coils to form a triple-stranded helical junction. The microtubule-binding region maps to within this triple-stranded junction, indicating that self-assembly creates hubs for effective microtubule interaction. Deletion of SSNA-1 in C. elegans reduces embryonic viability and causes multipolar spindles; impairing self-assembly has a comparable effect on embryonic viability to knockout. Cryo-EM structure determination, genetic knockout and self-assembly mutants in C. elegans, embryonic viability assays, spindle imaging Nature communications High 40804232
2025 SAS-1 (C2CD3 homologue) is essential for SSNA-1 localization to centrioles during oogenesis and to the transition zone during ciliogenesis in C. elegans. In a heterologous human cell assay, SAS-1 recruits SSNA-1 to microtubules. Molecular epistasis with null alleles establishes that SSNA-1 is positioned downstream of SAS-1 in the centriole integrity pathway, and SSNA-1 localizes adjacent to the SAS-1 C-terminus within centriole architecture.

2025 SSNA1 increases microtubule rigidity and resistance to breakage under force (kinesin-driven gliding and microfluidic flow assays). SSNA1 localization to damage sites prevents incorporation of new tubulin dimers, thereby inhibiting microtubule lattice self-repair. SSNA1 does not recognize damage sites that have been repaired by tubulin incorporation. In vitro reconstitution, TIRF microscopy, kinesin gliding assays, microfluidic force application, tubulin incorporation assays with purified proteins bioRxivpreprint Medium 41648615
2025 Using KO-validated antibodies and super-resolution/expansion microscopy, SSNA1 is shown to localize to the distal lumen of centrioles in a ring-like 9-fold symmetric configuration, separate from centriolar microtubules, and not in the nucleus, midbody, or ciliary axoneme as previously reported. SSNA1 KO impairs ciliogenesis by failing to facilitate CP110 removal. A C2CD3-SSNA1-LRRCC1 hierarchical targeting axis was identified in the distal lumen. Tag-free SSNA1 and microtubule co-pelleting assays indicate SSNA1 does not bind microtubules in vitro under these conditions.
