SOSS complex subunit A ; Sensor of single-strand DNA complex subunit A ; SOSS-A
Categories
Elisa
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.
Specificity
Natural and recombinant Mouse Integrator complex subunit 3
Subcellular Location
Nucleus Localizes to nuclear foci following DNA damage.
Belongs to the multiprotein complex Integrator, at least composed of INTS1, INTS2, INTS3, INTS4, INTS5, INTS6, INTS7, INTS8, INTS9/RC74, INTS10, CPSF3L/INTS11 and INTS12. Component of the SOSS complex, composed of SOSS-B (SOSS-B1/OBFC2B or SOSS-B2/OBFC2A), SOSS-A/INTS3 and SOSS-C/SSBIP1. SOSS complexes containing SOSS-B1/OBFC2B are more abundant than complexes containing SOSS-B2/OBFC2A. Interacts with SOSS-B1/OBFC2B, SOSS-B2/OBFC2A and SOSS-C/SSBIP1; the interaction is direct. Interacts with NBN/NBS1.
