Sigma Opioid Receptor[edit]

Is the sigma "opioid" receptor really a GPCR? From what is stated in the Sigma-1 receptor article, it almost certainly is not. Hence it should probably be listed as "Opioid (Delta, Kappa, Mu, Nociceptin, but not Sigma)". Boghog2 20:16, 9 May 2007 (UTC)[reply]

Sounds good to me. --Arcadian 22:05, 9 May 2007 (UTC)[reply]
