HSF2BP Interacts with a Conserved Domain of BRCA2 and Is Required for Mouse Spermatogenesis (Cell Reports)

BRCA2 is a key homologous recombination mediator in vertebrates. Brandsma et al. show that it directly interacts with a testis-expressed protein, HSF2BP, and that male mice deficient for HSF2BP are infertile due to a meiotic recombination defect. They also find that HSF2BP contributes to DNA repair in mouse embryonic stem cells.
