Is predicted to encode a protein with the following domains: Fibronectin type III superfamily; Immunoglobulin I-set domain; Immunoglobulin I-set; Fibronectin type III; Immunoglobulin-like fold; CD80-like C2-set immunoglobulin domain; Immunoglobulin subtype 2; Immunoglobulin domain; Immunoglobulin-like domain superfamily; Fibronectin type III domain; Immunoglobulin subtype; and CD80-like, immunoglobulin C2-set. Is an ortholog of C. elegans
syg-2. In C. elegans,
syg-2 is involved in cell-cell signaling; nervous system development; and protein localization to synapse.
