Is predicted to encode a protein with the following domains: SH3-like domain superfamily; SH3 domain; EF-hand domain pair; Variant SH3 domain; EH domain; and Cytoskeletal-regulatory complex EF hand. Is an ortholog of C. elegans
itsn-1. In C. elegans,
itsn-1 is involved in positive regulation of synaptic vesicle endocytosis.
