Protein Information (annotations from UniProt)

Database IDHIV0002358
UniProt IDO00487
Primary gene name(s)PSMD14
Synonym gene name(s)POH1
Protein name26S proteasome non-ATPase regulatory subunit 14
Protein functionMetalloprotease component of the 26S proteasome that specifically cleaves 'Lys-63'-linked polyubiquitin chains. The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. Plays a role in response to double-strand breaks, DSBs: acts as a regulator of non-homologous end joining, NHEJ by cleaving 'Lys-63'-linked polyubiquitin, thereby promoting retention of JMJD2A/KDM4A on chromatin and restricting TP53BP1 accumulation. Also involved in homologous recombination repair by promoting RAD51 loading. {ECO:0000269|PubMed:22909820, ECO:0000269|PubMed:9374539}.
