Abstract |
Since their proposal in 1976, the concept of sigma1 receptors has been continually evolving. Initially thought to be a member of the opioid receptor family, molecular studies have now identified its genes and established its structure crystallographically. Much effort has now revealed its importance as a chaperone in the endoplasmic reticulum, but its functions extend beyond this. Sigma1 receptors have been associated with a host of signaling systems. Evidence over the past 20 years has established the modulatory effects of sigma1 ligands on opioid systems. Despite their inability to bind directly to opioid receptors, sigma1 ligands can modulate opioid analgesia in vivo and signal transduction mechanisms in vitro. Furthermore, sigma1 receptors can physically associate with GPCRs. Together, these findings show that sigma1 ligands can function as allosteric modulators of GPCR function through their association with the sigma1 receptors, which are in direct physical association with opioid receptors, members of the G-protein coupled family of receptors. |
