FUNCTION: SwissProt: O15315 # Involved in the homologous recombination repair (HRR) pathway of double-stranded DNA breaks arising during DNA replication or induced by DNA-damaging agents. May promote the assembly of presynaptic RAD51 nucleoprotein filaments. The RAD51B- RAD51C dimer exhibits single-stranded DNA-dependent ATPase activity. The BCDX2 complex binds single-stranded DNA, single- stranded gaps in duplex DNA and specifically to nicks in duplex DNA.
SIZE: 384 amino acids; 42196 Da
SUBUNIT: Interacts with RAD51C. Part of a BCDX2 complex consisting of RAD51B, RAD51C, RAD51D and XRCC2. Part of a complex consisting of RAD51B, RAD51C, RAD51D, XRCC2 and XRCC3. Part of a complex with RAD51C and RAD51.
SUBCELLULAR LOCATION: Nucleus (Probable).
TISSUE SPECIFICITY: Expressed in a wide range of tissues.
DISEASE: SwissProt: O15315 # A chromosomal aberration involving RAD51L1 is found in pulmonary chondroid hamartoma. Translocation t(6;14)(p21;q23-24) with HMGA1. & A chromosomal aberration involving RAD51L1 is found in uterine leiomyoma (UL) [MIM:150699]. Translocation t(12;14)(q15;q23-24) with HMGA2.
SIMILARITY: SwissProt: O15315 ## Belongs to the recA family. RAD51 subfamily.
