Is predicted to encode a protein with the following domains: Immunoglobulin-like domain superfamily; Immunoglobulin domain; C-type lectin fold; and Immunoglobulin-like fold. Is an ortholog of C. elegans rig-6. In C. elegans, rig-6 is involved in several processes, including axon guidance; negative regulation of defecation rhythm; and regulation of locomotion.
