target relevance
Tyrosine hydroxylase (TH) is an enzyme critical for the synthesis of catecholamines, including dopamine, norepinephrine, and epinephrine. In research, TH has emerged as a vital cell marker, particularly for dopaminergic neurons. Dopaminergic neurons play essential roles in the brain's reward and motor systems and are implicated in various neurological disorders, such as Parkinson's disease and schizophrenia. TH immunohistochemistry, aided by specific antibodies targeting TH, allows researchers to identify and visualize dopaminergic neurons and assess their distribution and density in brain tissues. Additionally, these antibodies enable the quantification of TH levels, serving as a valuable tool for studying changes in dopaminergic function under different experimental conditions or in disease states. Furthermore, TH antibodies aid in the identification and analysis of TH-expressing cells in non-neuronal tissues, like the adrenal gland.

Catalyzes the conversion of L-tyrosine to L-dihydroxyphenylalanine (L-Dopa), the rate-limiting step in the biosynthesis of cathecolamines, dopamine, noradrenaline, and adrenaline. Uses tetrahydrobiopterin and molecular oxygen to convert tyrosine to L-Dopa (PubMed:17391063, PubMed:1680128, PubMed:15287903, PubMed:8528210, Ref.18, PubMed:34922205, PubMed:24753243). In addition to tyrosine, is able to catalyze the hydroxylation of phenylalanine and tryptophan with lower specificity (By similarity). Positively regulates the regression of retinal hyaloid vessels during postnatal development (By similarity). ; [Isoform 5]: Lacks catalytic activity. ; [Isoform 6]: Lacks catalytic activity.
Catalytic activity
Reaction=(6R)-L-erythro-5,6,7,8-tetrahydrobiopterin + L-tyrosine + O2 = (4aS,6R)-4a-hydroxy-L-erythro-5,6,7,8-tetrahydrobiopterin + L-dopa; Xref=Rhea:RHEA:18201, ChEBI:CHEBI:15379, ChEBI:CHEBI:15642, ChEBI:CHEBI:57504, ChEBI:CHEBI:58315, ChEBI:CHEBI:59560; EC=; Evidence=; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:18202; Evidence=;
Catecholamine biosynthesis; dopamine biosynthesis; dopamine from L-tyrosine: step 1/2.
Subellular location
Cytoplasm, perinuclear region Nucleus Cell projection, axon Cytoplasm Cytoplasmic vesicle, secretory vesicle, synaptic vesicle Note=When phosphorylated at Ser-19 shows a nuclear distribution and when phosphorylated at Ser-31 as well at Ser-40 shows a cytosolic distribution (By similarity). Expressed in dopaminergic axons and axon terminals.
Mainly expressed in the brain and adrenal glands.
Homotetramer (Ref.18, PubMed:24947669). Interacts (when phosphorylated at Ser-19) with YWHAG; one YWHAG dimer bounds to one TH tetramer, this interaction may influence the phosphorylation and dephosphorylation of other sites (PubMed:24947669).
Post-translational modification
Phosphorylated on Ser-19, Ser-62 and Ser-71 by several protein kinases with different site specificities. Phosphorylation at Ser-62 and Ser-71 leads to an increase of TH activity (PubMed:7901013). Phosphorylation at Ser-71 activates the enzyme and also counteracts the feedback inhibition of TH by catecholamines (PubMed:15287903). Phosphorylation of Ser-19 and Ser-62 triggers the proteasomal degradation of TH through the ubiquitin-proteasome pathway (By similarity). Phosphorylation at Ser-62 facilitates transport of TH from the soma to the nerve terminals via the microtubule network (PubMed:28637871). Phosphorylation at Ser-19 induces the high-affinity binding to the 14-3-3 protein YWHAG; this interaction may influence the phosphorylation and dephosphorylation of other sites (PubMed:24947669). Ser-19 increases the phosphorylation at Ser-71 in a hierarchical manner, leading to increased activity (By similarity).

ICC/IF-image-rabbit-anti-Tyrosine Hydroxylase-polyclonal-antibody-1383
Immunofluorescent analysis of rat brain section stained with rabbit pAb to tyrosine hydroxylase, 1383, dilution 1:10,000, in red and costained with mouse mAb to pNF-H dilution 1:1,000 in green. The blue is Hoechst staining of nuclear DNA. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45µM, and free-floating sections were stained with the above antibodies. The 1383 antibody stains the striatal TH expressing interneurons, while the pNF-H antibody labels axons from other neuronal cells.

Chromogenic immunostaining of a NBF fixed paraffin embedded human midbrain section with rabbit pAb to tyrosine hydroxylase, 1383, dilution 1:10,000, detected with DAB (brown) using the Vector Labs ImmPRESS method and reagents with citra buffer retrieval. Hematoxylin (blue) was used as the counterstain. In this image, 1383 antibody labels dopaminergic neurons and their axons traversing the striatum. This antibody performs well in testing with 4% PFA and standard NBF fixed mouse, rat and human tissue. Mouse select image for larger view.
