Opioid Receptor 1, Mu, Aa384-398 (OPRM1) Antibody – Rabbit Polyclonal

This gene encodes one of three opioid receptors. The mu opioid receptor is the principal target of endogenous opioid peptides and opioid analgesic agents such a s beta-endorphn and enkephalins. The NM_001008503.1:c.118A>G allele had been associated with opioid and alcohol addiction and variations in pain sensitivity but evidence is conflicting. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2012]

MOR-1: a Gi-protein-coupled receptor for beta-endorphin, morphine and other opiates. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Ligand-binding inactivates adenylyl cyclase, and activates a variety of G-beta-gamma-dependent pathways including the MAPK and the PI3K/Akt cascades. Two splice-variant isoforms have been described.
