Is predicted to encode a protein with the following domains: 7TM GPCR, serpentine receptor class r (Str); Serpentine type 7TM GPCR chemoreceptor Str; and Glycoside hydrolase superfamily. Is an ortholog of C. elegans
lys-4 and
lys-6. In C. elegans,
lys-4 is involved in defense response to Gram-positive bacterium.
