Previous GeneCards Identifiers for USP16 Gene
This gene encodes a deubiquitinating enzyme that is phosphorylated at the onset of mitosis and then dephosphorylated at the metaphase/anaphase transition. It can deubiquitinate H2A, one of two major ubiquitinated proteins of chromatin, in vitro and a mutant form of the protein was shown to block cell division. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
GeneCards Summary for USP16 Gene
USP16 (Ubiquitin Specific Peptidase 16) is a Protein Coding gene. Among its related pathways are Metabolism of proteins and Integrated Breast Cancer Pathway. Gene Ontology (GO) annotations related to this gene include transcription coactivator activity and cysteine-type endopeptidase activity. An important paralog of this gene is USP45.
UniProtKB/Swiss-Prot for USP16 Gene
Specifically deubiquitinates Lys-120 of histone H2A (H2AK119Ub), a specific tag for epigenetic transcriptional repression, thereby acting as a coactivator. Deubiquitination of histone H2A is a prerequisite for subsequent phosphorylation at Ser-11 of histone H3 (H3S10ph), and is required for chromosome segregation when cells enter into mitosis. In resting B- and T-lymphocytes, phosphorylation by AURKB leads to enhance its activity, thereby maintaining transcription in resting lymphocytes. Regulates Hox gene expression via histone H2A deubiquitination. Prefers nucleosomal substrates. Does not deubiquitinate histone H2B.
