Protein Information (annotations from UniProt)

Database IDHIV0001443
UniProt IDQ68E01
Primary gene name(s)INTS3
Synonym gene name(s)C1orf193, C1orf60
Protein nameIntegrator complex subunit 3
Protein functionComponent of the Integrator complex. The Integrator complex is involved in the small nuclear RNAs, snRNA U1 and U2 transcription and in their 3'-box-dependent processing. The Integrator complex is associated with the C-terminal domain, CTD of RNA polymerase II largest subunit, POLR2A and is recruited to the U1 and U2 snRNAs genes.; FUNCTION: Component of the SOSS complex, a multiprotein complex that functions downstream of the MRN complex to promote DNA repair and G2/M checkpoint. The SOSS complex associates with single-stranded DNA at DNA lesions and influences diverse endpoints in the cellular DNA damage response including cell-cycle checkpoint activation, recombinational repair and maintenance of genomic stability. The SOSS complex is required for efficient homologous recombination-dependent repair of double-strand breaks, DSBs and ATM-dependent signaling pathways. In the SOSS complex, it is required for the assembly of the complex and for stabilization of the complex at DNA damage sites.
Subcellular locationNucleus {ECO:0000269|PubMed:19605351, ECO:0000269|PubMed:19683501}. Note=Localizes to nuclear foci following DNA damage.
