    Product Information

    Product Description

    The rapid protocol (RP) PathScan® RP Phospho-Tyrosine Hydroxylase (Ser31) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of tyrosine hydroxylase protein phosphorylated at Ser31 in a reduced assay time of 1.5 hours. Incubation of cell lysates and detection antibody on the coated microwell plate forms a sandwich with phospho-tyrosine hydroxylase (Ser31) in a single step. The plate is then extensively washed and TMB reagent is added for signal development. The magnitude of absorbance for the developed color is proportional to the quantity of phospho-tyrosine hydroxylase (Ser31). Learn more about your ELISA kit options here.

    Protocol

    Specificity / Sensitivity

    The PathScan® RP Phospho-Tyrosine Hydroxylase (Ser31) Sandwich ELISA Kit detects endogenous levels of tyrosine hydroxylase protein phosphorylated at Ser31. The kit sensitivity is shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Species Reactivity:

    Human, Rat

    Background

    Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the synthesis of the neurotransmitter dopamine and other catecholamines. TH functions as a tetramer, with each subunit composed of a regulatory and catalytic domain, and exists in several different isoforms (1,2). This enzyme is required for embryonic development since TH knockout mice die before or at birth (3). Levels of transcription, translation and post-translational modification regulate TH activity. The amino-terminal regulatory domain contains three serine residues: Ser9, Ser31, and Ser40. Phosphorylation at Ser40 by PKA positively regulates the catalytic activity of TH (4-6). Phosphorylation at Ser31 by CDK5 also increases the catalytic activity of TH through stabilization of TH protein levels (7-9).
