TPH2, Human (His)

TPH2 Protein, an isozyme of tryptophan hydroxylase, is a member of the pterin-dependent aromatic acid hydroxylase family. TPH2 is selectively expressed only in the serotonergic neurons of the raphe nuclei and is a rate-limiting enzyme in the brain serotonin synthesis pathway. TPH2 plays a more prominent role in the 5-HT synthesis in the brain. Moreover, it is a key factor in maintaining normal serotonin transfer in the central nervous system. TPH2 Protein, Human (His) is the recombinant human-derived TPH2 protein, expressed by E. coli , with N-6*His labeled tag.
