Sigma 1 receptor action
The sigma-1 receptor (σ1R), one of two sigma receptor subtypes, is a chaperone protein at the endoplasmic reticulum (ER) 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 … See more The σ1 receptor is defined by its unique pharmacological profile. In 1976 Martin reported that the effects of N-allylnormetazocine (SKF-10,047) could not be due to activity at the μ and κ receptors (named from the … See more The mammalian σ1 receptor is an integral membrane protein with 223 amino acids.
