Is predicted to encode a protein with the following domains: Liprin-alpha; LAR-interacting protein, Liprin; Sterile alpha motif domain; SAM domain (Sterile alpha motif); and Sterile alpha motif/pointed domain superfamily. Is an ortholog of C. elegans syd-2. In C. elegans, syd-2 is involved in several processes, including anterograde synaptic vesicle transport; egg-laying behavior; and positive regulation of anterograde synaptic vesicle transport.
