Entrez Gene Summary for SIGMAR1 Gene

  • This gene encodes a receptor protein that interacts with a variety of psychotomimetic drugs, including cocaine and amphetamines. The receptor is believed to play an important role in the cellular functions of various tissues associated with the endocrine, immune, and nervous systems. As indicated by its previous name, opioid receptor sigma 1 (OPRS1), the product of this gene was erroneously thought to function as an opioid receptor; it is now thought to be a non-opioid receptor. Mutations in this gene has been associated with juvenile amyotrophic lateral sclerosis 16. Alternative splicing of this gene results in transcript variants encoding distinct isoforms.

UniProtKB/Swiss-Prot Summary for SIGMAR1 Gene

  • Functions in lipid transport from the endoplasmic reticulum and is involved in a wide array of cellular functions probably through regulation of the biogenesis of lipid microdomains at the plasma membrane. Involved in the regulation of different receptors it plays a role in BDNF signaling and EGF signaling. Also regulates ion channels like the potassium channel and could modulate neurotransmitter release. Plays a role in calcium signaling through modulation together with ANK2 of the ITP3R-dependent calcium efflux at the endoplasmic reticulum. Plays a role in several other cell functions including proliferation, survival and death. Originally identified for its ability to bind various psychoactive drugs it is involved in learning processes, memory and mood alteration (PubMed:16472803, PubMed:9341151). Necessary for proper mitochondrial axonal transport in motor neurons, in particular the retrograde movement of mitochondria. Plays a role in protecting cells against oxidative stress-induced cell death via its interaction with RNF112 (By similarity).

Tocris Summary for SIGMAR1 Gene

  • sigma1 receptors are members of the sigma family of receptors that also includes sigma2 receptors. They are distinguished from sigma2 receptors as they have high affinity and stereoselectivity for the (+)-isomers of pentazocine, SK&F 10047 and cyclazocine, and different subcellular localizations.

SGMR1_HUMAN
  • Amyotrophic lateral sclerosis 16, juvenile (ALS16) [MIM:614373]: A neurodegenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord, resulting in fatal paralysis. Sensory abnormalities are absent. The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. {ECO:0000269 PubMed:21842496}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Distal spinal muscular atrophy, autosomal recessive, 2 (DSMA2) [MIM:605726]: An autosomal recessive neuromuscular disorder characterized by onset of distal muscle weakness and wasting affecting the lower and upper limbs in the first decade. There is no sensory involvement. {ECO:0000269 PubMed:26078401, ECO:0000269 PubMed:27629094}. Note=The disease is caused by mutations affecting the gene represented in this entry.
