Is predicted to encode a protein with the following domains: Immunoglobulin-like fold; CD80-like C2-set immunoglobulin domain; Immunoglobulin-like domain superfamily; Immunoglobulin subtype; Immunoglobulin subtype 2; Immunoglobulin I-set domain; Immunoglobulin I-set; Immunoglobulin domain; and CD80-like, immunoglobulin C2-set. Is an ortholog of C. elegans
syg-1. In C. elegans,
syg-1 is involved in several processes, including actin filament bundle assembly; cell-cell adhesion; and nervous system development.
