This domain is found in Tyrosine 3-monooxygenase from Rattus norvegicus (TH) and similar proteins from vertebrates. TH catalyses the hydroxylation of tyrosine to form 3,4-dihydroxyphenylalanine in the biosynthesis of the catecholamine neurotransmitters. This entry represents the regulatory domain, which is centrally located (C- terminal to Pfam:PF12549 and N-terminal to Pfam:PF00351). It is an ACT domain that shows a four stranded antiparallel beta-sheet and two alpha-helices connected by four loops. It adopts a dimeric configuration [1-3]. In humans, TH is associated with several disorders [4].	Domain
