tyrosine 3-monooxygenase; Tyrosine 3-monooxygenase; tyrosine 3-monooxygenase; tyrosine 3-hydroxylase; tyrosine hydroxylase; Tyrosine 3-hydroxylase
other gene names :
Th; Th; The; TH
uniprot entry name :
TY3H_RAT
reactivity :
Many Mammalian/ Many Non-mammalian/
specificity :
Specific for the ~60k tyrosine hydroxylase protein phosphorylated at Ser40. Some higher molecular weight bands may be detected by the antibody depending upon the brain region being studied, protein loads and the detection methods used. The antibody has three orders of magnitude selectivity over dephospho TH.
purity :
Affinity Purified (Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephosphopeptide affinity columns.)
form :
100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western blots.
storage stability :
For long term storage -20 degree C is recommended. Stable at -20 degree C for at least 1 year.
tested application :
Western Blot (WB), Immunofluorescence (IF), Immunohistochemistry (IHC)
app notes :
Quality Control: Western blots performed on each lot. WB: 1:1000. IHC (frozen sections; Witkovsky et al., 2000): 1:1000. IF (frozen sections; Witkovsky et al., 2000): 1:1000
other info1 :
Antigen: Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser40 of rat tyrosine hydroxylase. Immunogen Information: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser40 conjugated to KLH. Immunogen Species: Rat
other info2 :
Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots with many mammalian and non-mammalian species. Biological Significance: Tyrosine hydroxylase (TH) is the rate-limiting enzyme in the synthesis of the catecholamines Dopamine and Norepinephrine. TH antibodies can therefore be used as markers for dopaminergic and noradrenergic neurons in a variety of applications including depression, schizophrenia, Parkinson's disease and drug abuse (Kish et al., 2001; Zhu et al., 2000; Zhu et al., 1999). TH antibodies can also be used to explore basic mechanisms of dopamine and norepinephrine signaling (Witkovsky et al., 2000; Salvatore et al., 2001; Dunkley et al., 2004). The activity of TH is also regulated by phosphorylation (Haycock et al., 1982; Haycock et al., 1992; Jedynak et al., 2002). Phospho-specific antibodies for the phosphorylation sites on TH can be used to great effect in studying this regulation and in identifying the cells in which TH phosphorylation occurs.

ncbi summary :
catalyzes the rate limiting step in catecholamine biosynthesis; may be involved in response to hypoxia [RGD, Feb 2006]
uniprot summary :
Function: Plays an important role in the physiology of adrenergic neurons. Catalytic activity: L-tyrosine + tetrahydrobiopterin + O2 = L-dopa + 4a-hydroxytetrahydrobiopterin. Cofactor: Fe2+ ion. Enzyme regulation: Phosphorylation leads to an increase in the catalytic activity. Pathway: Catecholamine biosynthesis; dopamine biosynthesis; dopamine from L-tyrosine: step 1/2. Subunit structure: Homotetramer. Post-translational modification: In vitro, phosphorylation of Ser-19 increases the rate of Ser-40 phosphorylation, which results in enzyme opening and activation. Sequence similarities: Belongs to the biopterin-dependent aromatic amino acid hydroxylase family.
