Previous GeneCards Identifiers for TPH2 Gene
This gene encodes a member of the pterin-dependent aromatic acid hydroxylase family. The encoded protein catalyzes the first and rate limiting step in the biosynthesis of serotonin, an important hormone and neurotransmitter. The human genome contains two related tryptophan hydroxylases, one on chromosome 11p15-p14 and one on chromosome 12q21. This gene is expressed predominantly in the brain stem. Mutations in this gene may be associated with psychiatric diseases such as bipolar affective disorder and major depression. [provided by RefSeq, Jul 2008]
GeneCards Summary for TPH2 Gene
TPH2 (Tryptophan Hydroxylase 2) is a Protein Coding gene. Diseases associated with TPH2 include tryptophan hydroxylase deficiency and major depressive disorder and accelerated response to antidepressant drug treatment. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include iron ion binding and tryptophan 5-monooxygenase activity. An important paralog of this gene is TPH1.
Hydroxylases are enzymes that catalyze the addition of -OH (hydroxyl) groups to their substrate during oxidation reactions. This diverse group of enzymes includes tryptophan hydroxylase (E.C. 22.214.171.124), which is involved in serotonin synthesis; steroid 11-beta hydroxylase (also known as CYP11B1) (E.C. 126.96.36.199), which is involved in glucocorticoid synthesis; and LTB4 omega-hydroxylase (also known as CYP4F3) (E.C. 188.8.131.52), which is involved in arachidonic acid metabolism.
