Is predicted to encode a protein with the following domains: IQ calmodulin-binding motif; CH domain superfamily; Calponin homology domain; IQ motif, EF-hand binding site; and Calponin homology (CH) domain. 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.
