Protein Information (annotations from UniProt)

Database IDHIV0008151
UniProt IDP60896
Primary gene name(s)SHFM1
Synonym gene name(s)DSS1, SHFDG1
Protein name26S proteasome complex subunit DSS1
Protein functionSubunit of the 26S proteasome which plays a role in ubiquitin-dependent proteolysis, PubMed:15117943. Component of the TREX-2 complex, transcription and export complex 2, composed of at least ENY2, GANP, PCID2, DSS1, and either centrin CETN2 or CETN3, PubMed:22307388. The TREX-2 complex functions in docking export-competent ribonucleoprotein particles, mRNPs to the nuclear entrance of the nuclear pore complex, nuclear basket. TREX-2 participates in mRNA export and accurate chromatin positioning in the nucleus by tethering genes to the nuclear periphery. Binds and stabilizes BRCA2 and is thus involved in the control of R-loop-associated DNA damage and thus transcription-associated genomic instability. R-loop accumulation increases in DSS1-depleted cells. {ECO:0000269|PubMed:15117943, ECO:0000269|PubMed:22307388, ECO:0000269|PubMed:24896180}.
