Synthesis pass · prose summary of the discoveries below

ASPM is a microtubule minus-end-associated protein that focuses spindle poles, regulates DNA damage responses, and co-activates Wnt/β-catenin signaling, with loss-of-function mutations causing autosomal recessive primary microcephaly. At spindle poles, ASPM autonomously tracks growing microtubule minus ends, cross-links microtubule bundles to focus poles, and forms a complex with the katanin p60/p80 severing enzyme—resolved by crystallography—to regulate spindle flux and microtubule disassembly; it acts redundantly with CDK5RAP2 in pole focusing and requires Polo kinase phosphorylation for centrosomal aster nucleation (PMID:26644514, PMID:28436967, PMID:28883092, PMID:11283617). Beyond the spindle, ASPM is recruited to DNA double-strand breaks in a PARP2-dependent manner where it stabilizes BRCA1 by blocking HERC2-mediated ubiquitination, and it localizes to stalled replication forks via RAD17 to promote RAD9/TopBP1 loading and ATR-CHK1 checkpoint activation (PMID:34142045, PMID:36161901). In neural progenitors, ASPM modulates Cyclin E ubiquitination and Cdk2/Cyclin E-dependent G1 progression, and stabilizes Dishevelled-3 against proteasomal degradation to potentiate canonical Wnt/β-catenin transcriptional activity, thereby maintaining the proliferative symmetric division mode required for cortical expansion (PMID:26581405, PMID:21937711, PMID:30266990).

  11. 2017 High

    The molecular interface between ASPM and katanin was solved at atomic resolution, and reconstitution demonstrated that ASPM autonomously tracks growing microtubule minus ends, inhibits their growth, and cooperates with katanin to promote severing and regulate spindle flux—providing the most detailed mechanistic picture of ASPM's spindle function.

2001 Drosophila Asp (ASPM ortholog) is a 220-kDa microtubule-associated protein that localizes to spindle poles independently of functional centrosomes; in asp mutants, microtubule nucleation occurs normally but spindle pole focusing and central spindle organization are severely defective, leading to cytokinesis failure. Asp is required for aggregation of microtubules into focused spindle poles and for formation of the central spindle. Genetic mutant analysis (asp mutants), immunofluorescence, double mutant epistasis with asterless, colchicine treatment The Journal of cell biology High 11352927
2001 Drosophila Asp is a substrate of Polo kinase; Polo phosphorylates Asp in vitro, generating an MPM2 epitope. Polo and Asp co-immunoprecipitate and exist in a 25–38S complex. Phosphorylated Asp is required (together with gamma-tubulin) to restore microtubule aster nucleation in salt-stripped centrosomes, and extracts from polo mutant embryos fail this rescue unless supplemented with phosphorylated Asp or active Polo kinase.

2005 Human ASPM localizes to the centrosome during interphase and to spindle poles from prophase through telophase; siRNA-mediated downregulation of ASPM decreases endogenous BRCA1 protein levels, suggesting ASPM regulates BRCA1 at the centrosome/spindle pole. siRNA knockdown, immunofluorescence, Western blot Cell cycle (Georgetown, Tex.) Medium 16123590
2005 RNAi depletion of Drosophila Asp in S2 cells produces severe loss of spindle pole focus; Asp localizes to focused poles and is subtly mislocalized after dynein-dynactin depletion, indicating complex interdependence between dynein-dynactin, Asp, and KLP10A in spindle pole focusing and centrosome attachment. RNAi depletion, immunofluorescence, quantitative spindle analysis Molecular biology of the cell Medium 15888542
2007 Human ASPM co-localizes with citron kinase (CITK) at the midbody ring during cytokinesis and co-immunoprecipitates with CITK from HeLa cell lysates and embryonic neuroepithelium. The N-terminal fragment of ASPM localizes to centrosomes/spindle poles, while the C-terminal fragment localizes to midbodies; all microcephaly-causing ASPM mutations truncate the C-terminus.

2010 Human ASPM is a microtubule minus-end-associated protein recruited in a microtubule-dependent manner to the pericentriolar matrix at spindle poles. siRNA depletion perturbs spindle orientation and causes cytokinesis failure in U2OS cells. A pathogenic splice-site mutation causing loss of a tripeptide from the C-terminus dramatically reduces ASPM spindle pole localization. Dominant-negative C-terminal ASPM fragments cause spindle assembly defects and cytokinesis failure. siRNA knockdown, immunofluorescence, live-cell imaging, patient fibroblast analysis, dominant-negative expression BMC cell biology High 21044324

2015 ASPM interacts with the Cdk2/Cyclin E complex and modulates Cyclin E ubiquitination and phosphorylation, thereby regulating nuclear translocation of Cyclin E and the timing of restriction point passage in neural progenitors.

2017 ASPM forms a complex with the microtubule-severing ATPase katanin (p60/p80 heterodimer). X-ray crystallography revealed that the N- and C-terminal domains of katanin p60 and p80, respectively, bind conserved motifs in ASPM. Reconstitution experiments showed ASPM autonomously tracks growing microtubule minus ends and inhibits their growth; katanin potentiates this minus-end blocking and, together with ASPM, promotes microtubule severing.

2017 Human ASPM functions redundantly with CDK5RAP2 (CEP215) in spindle pole focusing; ASPM gene knockout alone does not disrupt spindle morphology, but ASPM KO combined with CDK5RAP2 depletion causes spindle pole unfocusing during prometaphase and delayed anaphase onset. A microcephaly-associated hypomorphic ASPM mutation similarly caused pole unfocusing only in the absence of CDK5RAP2.
