Activity summary

Tryptophan Hydroxylase (TPH) is an enzyme that plays a critical mechanical role in the body. It is sometimes known as TPH or anti TPH. The enzyme catalyzes the conversion of tryptophan to 5-hydroxytryptophan the first and rate-limiting step in the biosynthesis of serotonin. The molecular mass of TPH is approximately 55 kDa. TPH has two isoforms TPH1 and TPH2 which are expressed in different tissues. TPH1 is mainly found in peripheral tissues such as the gut pineal gland and thymus while TPH2 is expressed in the central nervous system particularly in the raphe nuclei of the brainstem.

Biological function summary

Tryptophan hydroxylase serves an important role in serotonin production which impacts mood regulation sleep and other functions. TPH operates primarily as a homotetramer and requires biopterin oxygen and iron for its activity. Serotonin synthesized as a result acts as a neurotransmitter and hormone influencing various physiological processes. The differential expression of TPH1 and TPH2 allows for compartmentalized regulation of serotonin synthesis addressing both peripheral and central nervous system needs.

Pathways

TPH is central in the serotonin biosynthetic pathway a critical pathway for neuromodulation. It converts tryptophan into 5-hydroxytryptophan which is then decarboxylated to serotonin. TPH's function connects closely with other proteins in these pathways such as Aromatic L-amino acid decarboxylase which further processes 5-hydroxytryptophan into serotonin. This integration within the serotonin pathway highlights its importance in maintaining serotonin levels and consequently normal neurological function.

Associated diseases and disorders

Tryptophan hydroxylase has associations with mood disorders and irritable bowel syndrome (IBS). Altered TPH activity may lead to disruptions in serotonin levels influencing development and progression of these conditions. Studies often link TPH2 with depression and anxiety due to its central neural expression and role in serotonin synthesis. Meanwhile TPH1 expressed in peripheral tissues has connections to IBS where serotonin significantly affects gut motility and sensitivity. The relationship between these disorders and TPH offers insights into therapeutic targets to modulate serotonin levels for treatment strategies.
