| 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. Click for more on: cell markers and Tyrosine hydroxylase |

| Function 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=1.14.16.2; Evidence=; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:18202; Evidence=; |
| Pathway 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. |
| Tissues Mainly expressed in the brain and adrenal glands. |
| Structure 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). |

| Affinity purified 5799 conjugated with ALEXA647 reliably detects TH expressed in murine peripheral blood mononuclear cells (PBMC). Whole blood acquired from C57B6/J mice via cardiac puncture was diluted 1:1 in sterile PBS and layered on top of Ficoll-Histopaque (GE Healthcare, 17-1440-03) and centrifuged at 400g, room temperature, for 20 minutes with acceleration set to minimum and brakes off. Cells acquired from interface of Ficoll and whole blood were washed twice in sterile PBS, and immediately fixed on ice using the eBioscience Fixation/Permeablization kit (eBioscience, 88-8824-00) for 30 minutes, then washed twice with 1mL permeabilization buffer. Intracellular staining for TH was accomplished by addition of 2µL of affinity purified 5799 directly conjugated to Alexa647 in 100uL staining volume (1:50 dilution from stock antibody conjugate solution at 2.2mg/mL) and incubated at room temperature for 30 minutes. Following two washes in 1mL permeabilization buffer, data were immediately acquired on a Sony SP6800 Spectral Analyzer, and analyzed in a FCS Express 7 software (DeNovo) in the University of Florida ICBR cytometry lab. Data provided by Adithya Gopinath working in the lab of Habibeh Khoshbouei, University of FloridaClear separation of the positive sample (red) from negative control (black, chicken IgY plus anti-chicken Alexa647 conjugate) indicates clear staining and specificity of chicken anti-TH-647 for TH expressed in murine PBMCs, and shows suitability for flow cytometric analysis of murine PBMCs for TH expression. Further details about this interesting approach are found in Gopinath et al. (2020). |
