Enables 2',3'-cyclic-nucleotide 3'-phosphodiesterase activity. Acts upstream of or within adult locomotory behavior; neurogenesis; and response to toxic substance. Located in cytoplasm; membrane; and myelin sheath. Is expressed in adrenal gland; central nervous system; gut; peripheral nervous system; and reproductive system. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy 20; multiple sclerosis; and schizophrenia. Orthologous to human CNP (2',3'-cyclic nucleotide 3' phosphodiesterase).
