Is predicted to encode a protein with the following domains: GMP-PDE, delta subunit; Immunoglobulin E-set; GMP phosphodiesterase, delta subunit; and GMP phosphodiesterase, delta subunit superfamily. Is an ortholog of C. elegans unc-119. In C. elegans, unc-119 is involved in several processes, including body morphogenesis; dauer larval development; and regulation of multicellular organismal process.
