Summaries for USP21 Gene

Entrez Gene Summary for USP21 Gene

  • This gene encodes a member of the C19 peptidase family, also known as family 2 of ubiquitin carboxy-terminal hydrolases. The encoded protein cleaves ubiquitin from ubiquitinated proteins for recycling in intracellular protein degradation. The encoded protein is also able to release NEDD8, a ubiquitin-like protein, from NEDD8-conjugated proteins. This gene has been referred to as USP16 and USP23 but is now known as USP21. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for USP21 Gene

USP21 (Ubiquitin Specific Peptidase 21) is a Protein Coding gene. Among its related pathways are Integrated Breast Cancer Pathway and Ubiquitin-Proteasome Dependent Proteolysis. GO annotations related to this gene include transcription coactivator activity and cysteine-type peptidase activity. An important paralog of this gene is USP49.

UniProtKB/Swiss-Prot for USP21 Gene

  • 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 (By similarity). Also capable of removing NEDD8 from NEDD8 conjugates but has no effect on Sentrin-1 conjugates.

Molecular function for USP21 Gene

GENATLAS Biochemistry: ubiquitin specific protease 21,acting as an efficient deubiquitinating enzyme,deubiquitin enzyme family
UniProtKB/Swiss-Prot CatalyticActivity: Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal)
UniProtKB/Swiss-Prot 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.
