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).

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.

Monoclonal Anti-Tyrosine Hydroxylase (mouse IgG1 isotype) is derived from the TH-16 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from immunized BALB/c mice. Tyrosine hydroxylase (TH) exists in four isoforms in humans. They are are TH-1 (M.W. 55,600), TH-2 (4 additional amino acids; M.W. 56,000), TH-3, (27 additional amino acids; M.W. 58,100), and TH-4 (4 plus 27 additional amino acids; 58,500). Only humans express all four isoforms; all other anthropoids express only the TH-1 and TH-2 isoforms.

Specificity

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.
