{"product_id":"new-product-283734","title":"TPH1 polyclonal antibody","description":"\u003cp\u003ePhenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH) and tryptophan hydroxylase (TPH) comprise a small family of monooxygenases that use tetrahydropterine as a cofactor during the catabolism of aromatic L-amino acids. PAH, TH and TPH all contain catalytic domains with an amino-terminal regulatory domain and a short carboxy-terminal tetramerization domain. Each of these enzymes also contains a single ferrous iron atom, which is bound to two histidines and a glutamate and is likely to be involved in the formation of the hydroxylating intermediate. TPH is the first and rate-limiting step in the biosynthesis of serotonin in the central nervous system and melatonin in the pineal gland. Alteration of TPH function may be a key factor in the pathology of several neuropsychiatric disorders associated with serotonin, including depression, aggression, alcoholism and schizophrenia. For instance, L-DOPA, which is used as a common therapy for Parkinson’s disease (PD) patients, inhibits TPH function, which subsequently, is thought to contribute to the onset of depression in PD patients.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human, Mouse, Rat","offer_id":45809544986904,"sku":"ABCBW11824","price":448.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_9d49be86-728a-4246-b351-7654d29a9f91.png?v=1689759896","url":"https:\/\/danabiosci.com\/products\/new-product-283734","provider":"Dana Bioscience","version":"1.0","type":"link"}
