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; Immunoglobulin domain; Fibronectin type III superfamily; and Immunoglobulin I-set domain. Is an ortholog of C. elegans
unc-40. In C. elegans,
unc-40 is involved in several processes, including axon guidance; regulation of locomotion; and sex differentiation.
