For the detection of phosphoproteins, tyrosine phosphatase inhibitors such as 1mM sodium orthovanadate should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background. In Western blot, this antibody detects a band at ~55 kDa on lysates from human dorsal Raphe nucleus.
Tryptophan Hydroxylase (TPH) is a rate-limiting enzyme which catalyses the 5-hydroxylation of tryptophan, to form the amino acid 5-hydroxytryptophan (5-HTP), in the first stage of the biosynthesis of the neurotransmitter serotonin (5-hydroxytryptamine/5HT). Mammalian TPH is encoded by two genes: TPH1 expressed in peripheral tissues e.g. skin and gut, and TPH2 primarily expressed in the brain. Studies have demonstrated the regulation/enhancement of TPH activity through phosphorylation by cAMP-dependent protein kinase (PKA) and Ca2+/calmodulin kinase II (CaMKII), the latter of which phosphorylates a Ser19 site within the regulatory domain of TPH2.
