WebJul 16, 2024 · Sig-1R is an integral endoplasmic reticulum (ER) membrane protein which forms an oligomer and binds a variety of psychotropic drugs. It forms a complex with the ER chaperone BiP that controls specific signaling molecules’ stability and function at the ER to regulate Ca 2+ signaling, bioenergetics, and ER stress. WebA sigma-1 receptor creates a complex with the immunoglobulin heavy-chain-binding protein (BiP) chaperone located in the MAM; if calcium levels in the endoplasmic reticulum decrease, the sigma-1 receptor dissociates from the BiP. Sigma-1 receptors translocate readily when the endoplasmic reticulum is being affected by prolonged stressors.
