CC -!- FUNCTION: Component of the SOSS complex, a multiprotein complex that
CC functions downstream of the MRN complex to promote DNA repair and G2/M
CC checkpoint. In the SOSS complex, acts as a sensor of single-stranded
CC DNA that binds to single-stranded DNA, in particular to
CC polypyrimidines. The SOSS complex associates with DNA lesions and
CC influences diverse endpoints in the cellular DNA damage response
CC including cell-cycle checkpoint activation, recombinational repair and
CC maintenance of genomic stability. Required for efficient homologous
CC recombination-dependent repair of double-strand breaks (DSBs) and ATM-
CC dependent signaling pathways (By similarity). {ECO:0000250,
CC ECO:0000269|PubMed:16533169}.
CC -!- SUBUNIT: Component of the SOSS complex, composed of SOSS-B (SOSS-
CC B1/NABP2 or SOSS-B2/NABP1), SOSS-A/INTS3 and SOSS-C/INIP. SOSS
CC complexes containing SOSS-B1/NABP2 are more abundant than complexes
CC containing SOSS-B2/NABP1 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:16533169}.
CC Note=Localizes to nuclear foci following DNA damage. {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q8BGW5-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8BGW5-2; Sequence=VSP_033603;
CC -!- TISSUE SPECIFICITY: Ubiquitous with high expression in the thymus.
CC {ECO:0000269|PubMed:16533169}.
CC -!- SIMILARITY: Belongs to the SOSS-B family. SOSS-B2 subfamily.
CC {ECO:0000305}.
