PCBD2: Proteins and Enzymes

PCBD2, also known as Pterin-4-alpha-carbinolamine dehydratase 2, is a 130 amino acid protein that is 14 kDa, involved in tetrahydrobiopterin biosynthesis preventing the formation of 7-pterins and accelerating the formation of quinonoid-BH2, also being known to regulate the dimerization of homeodomain protein HNF-1-alpha and enhances its transcriptional activity. The protein is being studied for its involvement in hyperphenylalaninemia. The PCBD2 has also been shown to have interactions with DYRK1B, AATF, ASCC2, C1D, and CHAF1A in pathways such as phenylalanine degradation I (aerobic) pathway.
