Product Overview
Clone ADDO-21 is a rabbit monoclonal antibody that recognizes ubiquitin carboxyl-terminal hydrolase 28 (gene USP28) in human samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 122.5 kDa, and the supplier reports an observed band at about 135 kDa.
USP28 is a deubiquitinating enzyme that protects several proteins from degradation. It stabilizes the MYC oncoprotein by counteracting the ubiquitin ligase FBW7, and it supports DNA damage checkpoint signaling through proteins such as claspin and 53BP1. USP28 is studied in the DNA damage response and cancer.
