Meiotic recombination factor component of recombination bridges involved in meiotic double-strand break repair (PubMed:32463460, PubMed:32460033). Modulates the localization of recombinases DMC1:RAD51 to meiotic double-strand break (DSB) sites through the interaction with and stabilization of the BRCA2:HSF2BP complex during meiotic recombination (PubMed:32460033, PubMed:32463460). Indispensable for the DSB repair, homologous synapsis, and crossover formation that are needed for progression past metaphase I, is essential for spermatogenesis and male fertility (PubMed:32463460, PubMed:32460033). Interacts with HSF2BP (via N-terminus) and BRCA2; the interaction with HSF2BP is direct and allows the formation of a ternary complex (PubMed:32345962, PubMed:32460033, PubMed:32463460, PubMed:32845237). The complex BRME1:HSF2BP:BRCA2 interacts with SPATA22, MEIOB and RAD51 (PubMed:32345962). During meiosis, recruited to chromosomes and localizes on recombination sites in a double-strand break-dependent manner. First appears on the chromosome axis at leptotene. Along with the progression of meiotic recombination, released from the axis to form bridge-like structures linking homolog axes before they are synapsed. Finally, located between synapsed homolog axes and on the synaptonemal complex (SC). Expressed in testis. Expressed in fetal ovaries but not in adult ovaries. Male mutants are infertile (PubMed:32463460, PubMed:32460033, PubMed:32345962). They have smaller-than-normal testes with reduced diameters of seminiferous tubules and sperm density (PubMed:32460033, PubMed:32345962). Female mutants exhibit normal fertility with no apparent defect in adult ovaries (PubMed:32460033, PubMed:32345962). They show a strong reduction of the follicle pool.
