Anti-phospho USP7 (Ser18) Antibody

Ubiquitin-specific-processing protease 7 (USP7) is also known as Ubiquitin carboxyl-terminal hydrolase 7 or Herpesvirus-associated ubiquitin-specific protease (HAUSP). USP7 is a ubiquitin specific protease or a deubiquitylating enzyme that cleaves ubiquitin from its substrates. Since ubiquitylation (polyubiquitination) is most commonly associated with the stability and degradation of cellular proteins, USP7 activity generally stabilizes its substrate proteins, and it is most popularly known as a direct antagonist of Mdm2, the E3 ubiquitin ligase for the tumor suppressor protein, p53.

~140 kDa observed

Epitope: Near N-terminus

KLH-conjugated linear peptide corresponding to a region near the N-terminus of human USP7 phosphorylated at Ser18.

Peptide Inhibition Analysis: 0.2 µg/mL from a representative lot was blocked by a phospho-peptide in HeLa cell lysate.

Western Blotting Analysis: 0.02 µg/mL from a representative lot detected phospho USP7 (Ser18) in HeLa cell lysate (Prof. Grigory Dianov, University of Oxford, U.K.).

Western Blotting Analysis: 0.02 µg/mL from a representative lot detected 100 ng of phospho USP7 (Ser18), and not dephosphorylated USP7 (Prof. Grigory Dianov, University of Oxford, U.K.).
