Gene: Oprm1 (opioid receptor, mu 1) Mus musculus
Symbol: Oprm1
Name: opioid receptor, mu 1
Description: Exhibits opioid receptor activity. Involved in several processes, including adenylate cyclase-modulating G protein-coupled receptor signaling pathway; positive regulation of neurogenesis; and sensory perception of pain. Localizes to the membrane. Predicted to colocalize with the sarcolemma. Used to study autism spectrum disorder. Is expressed in central nervous system; peripheral nervous system; retina inner nuclear layer; stomach; and uterus. Orthologous to human OPRM1 (opioid receptor mu 1).
Type: protein-coding
RefSeq Status: REVIEWED
