About Sigma-1 Receptor


The sigma-1 receptor, one of two sigma receptor subtypes, is a chaperone protein at the endoplasmic reticulum that modulates calcium signaling through the IP3 receptor. In humans, the σ₁ receptor is encoded by the SIGMAR1 gene. The σ₁ receptor is a transmembrane protein expressed in many different tissue types.
