Scientific Data Images for VHR Antibody (237020)

Detection of Human, Mouse, and Rat VHR antibody by Western Blot.

Detection of Human, Mouse, and Rat VHR by Western Blot.

Western blot shows lysates of TE-85 human osteogenic sarcoma cell line, TF-1 human erythroleukemic cell line, and C2C12 mouse myoblast cell line. PVDF membrane was probed with 0.5 µg/mL Mouse Anti-Human/Mouse/ Rat VHR Monoclonal Antibody (Catalog # MAB1654) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, Recombinant Human VHR (Catalog # 1654-VH) (2 ng) was included. A specific band for VHR was detected at approximately 24 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: VHR

Vaccinia Virus VH1-related Phosphatase (VHR), also known as Dual-Specificity Phosphatase 3 (DUSP3), removes inorganic phosphate groups covalently attached to tyrosine, serine and threonine residues in proteins (1). It belongs to a family of phosphatases that selectively dephosphorylate MAP kinases. VHR has been shown to dephosphorylate cellular ERK1, ERK2 and JNK, but not p38 (2, 3). Phosphorylation of VHR at tyrosine 138 by ZAP-70 enhances inhibition of ERK2, suggesting a role for VHR in modulating T-cell receptor responses (3). The enzymatic mechanism for VHR has been studied in detail (4) and its X-ray crystal structure has been characterized (5). Its well-defined biochemistry has made it useful in screening assays for compounds that inhibit phosphatases (6).
