Is predicted to encode a protein with the following domains: Calponin homology (CH) domain; IQ calmodulin-binding motif; Calponin homology domain; IQ motif, EF-hand binding site; and CH domain superfamily. Is an ortholog of C. elegans aspm-1. In C. elegans, aspm-1 is involved in establishment of meiotic spindle orientation; meiotic spindle organization; and regulation of protein localization.
