| + | [https://www.uniprot.org/uniprot/5HT2A_HUMAN 5HT2A_HUMAN] G-protein coupled receptor for 5-hydroxytryptamine (serotonin) (PubMed:1330647, PubMed:18703043, PubMed:19057895). Also functions as a receptor for various drugs and psychoactive substances, including mescaline, psilocybin, 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) and lysergic acid diethylamide (LSD) (PubMed:28129538). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors (PubMed:28129538). Beta-arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways (PubMed:28129538). Signaling activates phospholipase C and a phosphatidylinositol-calcium second messenger system that modulates the activity of phosphatidylinositol 3-kinase and promotes the release of Ca(2+) ions from intracellular stores (PubMed:18703043, PubMed:28129538). Affects neural activity, perception, cognition and mood (PubMed:18297054). Plays a role in the regulation of behavior, including responses to anxiogenic situations and psychoactive substances. Plays a role in intestinal smooth muscle contraction, and may play a role in arterial vasoconstriction.<ref>PMID:1330647</ref> <ref>PMID:18297054</ref> <ref>PMID:18703043</ref> <ref>PMID:19057895</ref> <ref>PMID:21645528</ref> <ref>PMID:22300836</ref> <ref>PMID:28129538</ref> (Microbial infection) Acts as a receptor for human JC polyomavirus/JCPyV.<ref>PMID:24089568</ref> | ||

| + | There is currently a resurgence in exploring the utility of classical psychedelics to treat depression, addiction, anxiety disorders, cluster headaches, and many other neuropsychiatric disorders. A biological target of these compounds, and a hypothesized target for their therapeutic actions, is the 5-HT(2A) serotonin receptor. Here, we present 7 cryo-EM structures covering all major compound classes of psychedelic and non-psychedelic agonists, including a beta-arrestin-biased compound RS130-180. Identifying the molecular interactions between various psychedelics and the 5-HT(2A) receptor reveals both common and distinct motifs among the examined psychedelic chemotypes. These findings lead to a broader mechanistic understanding of 5-HT(2A) activation, which can catalyze the development of novel chemotypes with potential therapeutic utility and fewer side effects. | ||
