The function of Ensembl gene identifier ENSG00000165181 (SHOC1, shortage in chiasmata 1) is as follows. ATPase required during meiosis for the formation of crossover recombination intermediates (By similarity). Binds DNA: preferentially binds to single-stranded DNA and DNA branched structures (PubMed:29742103). Does not show nuclease activity in vitro, but shows ATPase activity, which is stimulated by the presence of single-stranded DNA (PubMed:29742103). Plays a key role in homologous recombination and crossing-over in meiotic prophase I in male and female germ cells (By similarity). Required for proper synaptonemal complex assembly and homologous chromosome pairing (By similarity). Requiref for recruitment TEX11 and MSH4 to recombination intermediates (By similarity). .
