Official Full Name: sigma non-opioid intracellular receptor 1
Also known as: SRBP; ALS16; DSMA2; OPRS1; SR-BP; SIG-1R; SR-BP1; sigma1R; hSigmaR1
The gene encodes a receptor protein that interacts with a variety of psychomimetic drugs, including cocaine and amphetamines. This receptor is thought to play an important role in the cellular functions of various tissues related to the endocrine, immune and nervous systems. Like its previous name, Opioid Receptor Sigma 1 (OPRS1), the product of this gene was mistakenly identified as an opioid receptor; it is now thought to be a non-opioid receptor. Mutations in this gene have been linked to juvenile amyotrophic lateral sclerosis. Alternative splicing of this gene results in transcript variants encoding different isoforms.
