The tryptophan hydroxylase 1 (TPH1) gene spanning 29kbp with 11 exons is mapped to human chromosome 11p15.3-p14. TPH1, is a 444 amino acid protein expressed in the gut, spleen, thymus and also in the pineal gland and the pituitary.
Tryptophan Hydroxylase (TPH) is a member of the aromatic amino acid hydroxylases (AAAH) family.
Immunogen
recombinant rabbit tryptophan hydroxylase, isolated as inclusion bodies from E. coli and purified by preparative SDS-PAGE.
Application
Anti-Tryptophan Hydroxylase antibody produced in sheep has been used in:
immunocytochemistry
immunohistochemistry
immunofluorescence
immunoperoxidase staining
Biochem/physiol Actions
The tryptophan hydroxylase 1 gene (TPH1) catalyzes the synthesis of 5-hydroxytryptophan, which is a precursor to the neurotransmitter serotonin. Variation in the gene expression affects prefrontal cortex activation during response inhibition. Mutation in the TPH1 gene leads to schizophrenia, irritable bowel syndrome (IBS) in women, suicidal behavior and depressive disorders. The encoded protein plays a vital role in regulation of cardiovascular function.

Serotonergic neurons in the dorsal raphe nucleus (DR) are organized in anatomically distinct subregions that form connections with specific brain structures to modulate diverse behaviors, including anxiety-like behavior. It is unclear if the functional heterogeneity of these neurons is coupled
Serotonin plays an important role in the regulation of anxiety states and physiological responses to aversive stimuli. Intracerebroventricular (i.c.v.) injection of the stress- and anxiety-related neuropeptide urocortin 2 (Ucn 2) increases c-Fos expression in serotonergic neurons in the dorsal (DRD)
Early adolescent adversity increases adult risk for anxiety disorders. The ventrolateral periaqueductal gray (vlPAG) and neighboring dorsal raphe (DR) are integral to threat prediction, and are responsive to acute stressors. Here, we tested the hypothesis that early adolescent adversity reshapes
GABAergic neurons in the dorsal raphe nucleus that express 5-HT3A receptors participate in responses to stress hormones
