rat tyrosine hydroxylase (TH).

General description

Tyrosine hydroxylase (TH) is encoded by the gene mapped to human chromosome 11p15. TH is a tetramer of four identical subunits, which is characterized with a regulatory, catalytic and tetramerization domains. The enzyme utilizes tyrosine, tetrahydrobiopterin (BH4) and O2 as cosubstrates, and Fe2+ as a cofactor.


The antibody recognizes an epitope present in the N-terminal region (between aa 40-152) of both rodent and human tryosine hydroxylase. TH-16 detects both the intact subunits and the 59/57 kDa doublet and an array of decreasing molecular weight TH forms resulting from severe proteolysis.


Monoclonal Anti-tyrosine hydroxylase antibody produced in mouse has been used in immunohistochemistry and double immunofluorescence labeling.

Biochem/physiol Actions

Tyrosine hydroxylase (TH) catalyzes the first rate limiting step in the biosynthesis of catecholamine neurotransmitter i.e. the conversion of L-tyrosine to L-dopa. Inhibition of TH by L-phenylalanine, might play a crucial role in phenylketonuria and block the synthesis of norepinephrine. Activity of TH can be regulated by phosphorylation. Decreased expression of TH is associated with various neuropsychiatric diseases such as schizophrenia and Parkinson’s disease (PD).
