Protein: Abnormal spindle-like microcephaly-associated protein homolog (Calmodulin-binding protein Sha1) (Calmodulin-binding protein 1) (Spindle and hydroxyurea checkpoint abnormal protein) (Q8CJ27)
Organism: Mus musculus (Mouse)
Function: Involved in mitotic spindle regulation and coordination of mitotic processes. The function in regulating microtubule dynamics at spindle poles including spindle orientation, astral microtubule density and poleward microtubule flux seem to depend on its association with the katanin complex formed by KATNA1 and KATNB1. Enhances the microtubule lattice severing activity of KATNA1 by recruiting the katanin complex to microtubules. Can block microtubule minus-end growth and reversely this function can be enhanced by the katanin complex. May have a preferential role in regulating neurogenesis.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:9819352}. Cytoplasm, cytoskeleton, spindle {ECO:0000269|PubMed:28436967}. Nucleus {ECO:0000269|PubMed:9819352}. Note=Localizes to spindle poles during mitosis. Associates with microtubule minus ends (PubMed:28436967). The nuclear-cytoplasmic distribution could be regulated by the availability of calmodulin. {ECO:0000269|PubMed:28436967}.
