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