Is predicted to encode a protein with the following domains: Basigin-like; Fibronectin type III domain; Fibronectin type III superfamily; Fibronectin type III; and Immunoglobulin-like fold. Is an ortholog of C. elegans lad-2. In C. elegans, lad-2 is involved in anterior/posterior axon guidance; dorsal/ventral axon guidance; and regulation of axon guidance.
