Product Overview
This rabbit polyclonal antibody recognizes 26S proteasome regulatory subunit 6B (gene PSMC4) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry, immunoprecipitation and ELISA. The predicted molecular weight is 47.4 kDa, and the supplier reports an observed band at about 47 kDa.
PSMC4 (Rpt3) is an AAA+ ATPase subunit of the 19S regulatory particle of the 26S proteasome. It contributes to substrate unfolding and gate opening of the 20S core, and it assembles into the base subcomplex with the help of dedicated chaperones such as PSMD10 (gankyrin).
