Predicted to enable cAMP binding activity; calcium- and calmodulin-regulated 3',5'-cyclic-GMP phosphodiesterase activity; and calmodulin-dependent cyclic-nucleotide phosphodiesterase activity. Acts upstream of or within sensory perception of smell. Located in cilium. Is expressed in several structures, including alimentary system; integumental system; male reproductive gland or organ; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 74. Orthologous to human PDE1C (phosphodiesterase 1C). [provided by Alliance of Genome Resources, Apr 2022]
