Tryptophan Hydroxylase pS260 antibody detects Tryptophan Hydroxylase, which catalyzes the 5-hydroxylation of tryptophan, which is the first step in the biosynthesis of indoleamines (serotonin and melatonin). In mammals, serotonin biosynthesis occurs predominantly in neurons which originate in the Raphe nuclei of the brain, and melatonin synthesis takes place within the pineal gland. Although TPH catalyzes the same reaction within the Raphe nuclei and the pineal gland, TPH activity is rate-limiting for serotonin but not melatonin biosynthesis. Serotonin functions mainly as a neurotransmitter, whereas melatonin is the principal hormone secreted by the pineal gland. The activity of TPH is enhanced by phosphorylation by cAMP-dependent protein kinase (PKA) and Ca2+/calmodulin kinase II (CaM K II). CaM K II phosphorylates Ser260 which lies within the regulatory domain of TPH. Anti-THPpS260 Antibody is ideal for investigators involved in Cell Signaling, and Neuroscience research.

Application Note

Anti-Tryptophan Hydroxylase pS260 (Rabbit) antibody is tested for use in Western Blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band of 55 kDa in size corresponding to typtophan hydroxylase protein phosphorylated at Ser260 in the appropriate cell lysate or extract. Researchers should determine optimal titers for applications that are not stated below.


Anti-Tryptophan Hydroxylase pS260 antibody is directed against rat Tryptophan Hydroxylase. Tryptophan Hydroxylase pS260 antibodies are affinity purified from monospecific antiserum by immunoaffinity purification. Reactivity is expected from the following species based on 100% sequence homology: bovine, canine, chicken, mouse and zebra fish.
