Informations générales

USP21(Ubiquitin carboxyl-terminal hydrolase 21) is also named as USP23.The USPs belong to a subclass of the protein-deubiquitinating enzyme (DUB) superfamily that are categorized into five subclasses based on their ubiquitin-protease domains in the human genome and have been shown to be involved in a broad range of biological activities(PMID:19910467). USP21 is expressed at different levels in the tissues examined. The highest level of USP21 expression is found in the heart, pancreas, and skeletal muscle. USP21 messages could also be detected in the brain, placenta, liver, and kidney but are very low in the Lung through the northern blot(PMID:10799498).

Detection of a protein at the expected size in the cell extracts in WB. Unfortunately, the signal is not loss when USP21 had been knocked down with 2 different pairs of siRNA raised against this protein. This antibody then likely recognizes a non specific band.
