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
sax-3. In C. elegans,
sax-3 is involved in generation of neurons and regulation of sensory neuron axon guidance.
