      Key Mechanism Factor 1
Factor Name 5-HT receptor Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
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.

Gene Name MAOB
Uniprot ID AOFB_HUMAN
KEGG Pathway hsa:4129
Protein Family Flavin monoamine oxidase family
Protein Function
Catalyzes the oxidative deamination of primary and some secondary amines such as neurotransmitters, and exogenous amines including the tertiary amine, neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), with concomitant reduction of oxygen to hydrogen peroxide and participates in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079). Preferentially degrades benzylamine and phenylethylamine (PubMed:11134050, PubMed:8665924, PubMed:8316221, PubMed:11049757, PubMed:20493079).

      Mechanism Description
  • Additive serotonergic effects by the combination of Tryptophan and Ozanimod 

Recommended Action
      Management Until more information is available, concomitant use of ozanimod with serotonergic agents should be avoided when possible. Blood pressure and other vitals should be monitored if coadministration is required.
