Is predicted to encode a protein with the following domains: WW domain; Guanylate kinase/L-type calcium channel beta subunit; P-loop containing nucleoside triphosphate hydrolase; PDZ superfamily; Guanylate kinase; PDZ domain; and WW domain superfamily. Is an ortholog of C. elegans
magi-1. In C. elegans,
magi-1 is involved in habituation; long-term memory; and regulation of protein localization.
