Enables chromatin binding activity; single-stranded DNA 3'-5' exodeoxyribonuclease activity; and single-stranded DNA binding activity. Involved in double-strand break repair via homologous recombination; fertilization; and meiosis I. Acts upstream of or within male meiotic nuclear division. Located in cytoplasm. Is expressed in genitourinary system. Human ortholog(s) of this gene implicated in spermatogenic failure 22. Orthologous to human MEIOB (meiosis specific with OB-fold).
