• function: Plays a role in DNA double-strand break (DBS) repair via homologous recombination (HR). Serves as a scaffolding protein that helps to promote the recruitment of DNA-processing enzymes like the helicase BLM and recombinase RAD51 to site of DNA damage, and hence contributes to maintain genomic integrity.
  subunit: Found in a complex, at least composed of BLM, RAD51 and SPIDR; the complex formation is mediated by SPIDR. Interacts (via C-terminal region) with BLM; the interaction is direct. Interacts with RAD51; the interaction is direct. Interacts (via the C-terminal region) with FIGNL1 (via N-terminal one-half region); the interaction is direct.
