Secondary Accession Numbers Not Available
Name Ubiquitin carboxyl-terminal hydrolase 21
Description Not Available
Synonyms
  1. Deubiquitinating enzyme 21
  2. Ubiquitin thiolesterase 21
  3. Ubiquitin-specific-processing protease 21
Gene Name USP21
Protein Type Enzyme
Biological Properties
General Function Involved in ubiquitin thiolesterase activity
Specific Function Deubiquitinates histone H2A, a specific tag for epigenetic transcriptional repression, thereby acting as a coactivator. Deubiquitination of histone H2A releaves the repression of di- and trimethylation of histone H3 at 'Lys-4', resulting in regulation of transcriptional initiation. Regulates gene expression via histone H2A deubiquitination. Also capable of removing NEDD8 from NEDD8 conjugates but has no effect on Sentrin-1 conjugates
