General description

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.

Physical form

Solution in 150 mM NaCl, 10 mM HEPES, pH 7.5, 100 μg per mL BSA, and 50% glycerol.

Prior adverse experience alters behavioral responses to subsequent stressors. For example, exposure to a brief swim increases immobility in a subsequent swim test 24h later. In order to determine if qualitative differences (e.g. 19°C versus 25°C) in an initial stressor

Tryptophan hydroxylase is the rate-limiting enzyme in the biosynthesis of serotonin (5-hydroxytryptamine; 5-HT). Two isoforms of tryptophan hydroxylase, derived from different genes, tph1 and tph2, have been identified. The tph1 isoform is expressed in peripheral tissues, whereas tph2 is brain

Aversive, positive prediction error (+PE) provides a mechanism to update and increase future fear to uncertain threat predictors. The ventrolateral periaqueductal grey (vlPAG) has been offered as a neural locus for +PE computation. Yet, a causal demonstration of vlPAG +PE

Faced with potential harm, individuals must estimate the probability of threat and initiate an appropriate fear response. In the prevailing view, threat probability estimates are relayed to the ventrolateral periaqueductal gray (vlPAG) to organize fear output. A straightforward prediction is
