Involved in DNA methylation and negative regulation of transposition. Acts upstream of or within several processes, including male gamete generation; regulation of double-strand break repair via homologous recombination; and synaptonemal complex assembly. Located in cytoplasm and nucleus. Is expressed in meninges; oocyte; sensory organ; and spinal cord mantle layer. Human ortholog(s) of this gene implicated in spermatogenic failure 25. Orthologous to human TEX15 (testis expressed 15, meiosis and synapsis associated). [provided by Alliance of Genome Resources, Apr 2022]
