CC -!- FUNCTION: Involved in the homologous recombination repair (HRR) pathway
CC of double-stranded DNA, thought to repair chromosomal fragmentation,
CC translocations and deletions. Part of the RAD21 paralog protein complex
CC CX3 which acts in the BRCA1-BRCA2-dependent HR pathway. Upon DNA
CC damage, CX3 acts downstream of RAD51 recruitment; the complex binds
CC predominantly to the intersection of the four duplex arms of the
CC Holliday junction (HJ) and to junctions of replication forks. Involved
CC in HJ resolution and thus in processing HR intermediates late in the
CC DNA repair process; the function may be linked to the CX3 complex and
CC seems to involve GEN1 during mitotic cell cycle progression. Part of a
CC PALB2-scaffolded HR complex containing BRCA2 and RAD51C and which is
CC thought to play a role in DNA repair by HR. Plays a role in regulating
CC mitochondrial DNA copy number under conditions of oxidative stress in
CC the presence of RAD51 and RAD51C (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with RAD51C and RAD51. Part of the CX3 complex
CC consisting of RAD51C and XRCC3; the complex has a ring-like structure
CC arranged into a flat disc around a central channel; CX3 can interact
CC with RAD51 in vitro. Forms a complex with FANCD2, BRCA2 and
CC phosphorylated FANCG. Interacts with SWSAP1 and ZSWIM7; involved in
CC homologous recombination repair. Interacts directly with PALB2 which
CC may serve as a scaffold for a HR complex containing PALB2, BRCA2,
CC RAD51C, RAD51 and XRCC3 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Cytoplasm, perinuclear region {ECO:0000250}. Mitochondrion matrix
CC {ECO:0000250}. Note=Accumulates in discrete nuclear foci prior to DNA
CC damage, and these foci persist throughout the time course of DNA
CC repair. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the RecA family. RAD51 subfamily. {ECO:0000305}.
