Is predicted to encode a protein with the following domains: P-loop containing nucleoside triphosphate hydrolase; PDZ domain; WW domain; WW domain superfamily; Guanylate kinase/L-type calcium channel beta subunit; Guanylate kinase; and PDZ 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.
