Oprm1 - opioid receptor, mu 1

Enables several functions, including G-protein beta-subunit binding activity; filamin binding activity; and morphine receptor activity. Involved in several processes, including G protein-coupled receptor signaling pathway; regulation of signal transduction; and response to alkaloid. Located in several cellular components, including dendrite; focal adhesion; and perikaryon. Is active in spine apparatus. Is integral component of postsynaptic membrane and integral component of presynaptic membrane. Colocalizes with sarcolemma. Biomarker of brain ischemia and human immunodeficiency virus infectious disease. Orthologous to human OPRM1 (opioid receptor mu 1). [provided by Alliance of Genome Resources, Apr 2022]
