Summary: Enables tyrosine 3-monooxygenase activity. Acts upstream of or within dopamine biosynthetic process and spinal cord motor neuron differentiation. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in axon; cytoplasm; and perikaryon. Is expressed in several structures, including chromaffin cell; digestive system; head; nervous system; and posterior presumptive neural plate. Human ortholog(s) of this gene implicated in Parkinson's disease; Parkinsonism; hypertension; and obesity. Orthologous to human TH (tyrosine hydroxylase).

th1 is predominant in the brain of zebrafish and th2 in the periphery.
Title: Complementary developmental expression of the two tyrosine hydroxylase transcripts in zebrafish.
The developmental sequence of THir cell groups in dogfish appears to be rather similar to that described for teleosts, apart from the appearance of the ventral tegmental area/substantia nigra and pallial cells, which lack in teleosts.

In the analyzed samples we found two novel TH mRNAs, one lacking exon 8, and another lacking exons 8+9. These new splicing variants are described in a region of TH previously reported to be conserved.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
