Double-strand-break repair protein rad21-like protein 1 (RAD21L1)

Meiosis-specific part of some cohesin complex required during the initial steps of prophase I in male meiosis. Probably required during early meiosis in males for separation of sister chromatids and homologous chromosomes.

Replaces RAD21 at premeiotic S phase (during first stages of prophase I), while RAD21 reappears in later stages of prophase I. involved with synaptonemal complex assembly, synapsis initiation and crossover recombination between homologous chromosomes during prophase I (By similarity).
