The fungal protein ERG2, a C-8 sterol isomerase, falls into the same protein family as sigma-1. Both localize to the ER membrane, although sigma-1 is also reported to be a cell surface receptor. Sigma-2 is an EXPERA domain protein [4] with a mostly intracellular (ER membrane) localization. [5]
The σ 1 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 first letter of their selective ligands morphine and ketazocine, respectively) and a new type of opioid receptor was proposed; σ (from the first letter of SKF-10,047).

In biology, the sigma receptor (σ–receptors) is a type of cell surface receptor. In biochemistry, the σ factor (or specificity factor) is a protein found in RNA polymerase. In bone physiology, the bone remodeling period—i.e., the life span of a basic multicellular unit—has historically been referred to as the sigma period.
Theater lovers and movie goers alike have been counting down the days until the film adaptation of Broadway’s Wicked premieres. Wicked made its stage debut in 2003, with Idina Menzel and Kristin ...
Sigma receptors are defined by the presence of one amine binding site and three hydrophobic binding sites nearby in the ligand-binding region. [4] Thus, the N(b) atom in the central piperazine ring serves to interact with the amine binding site and the two phenethyl groups serve to fill two out of the three hydrophobic pockets.
