Enables sequence-specific DNA binding activity. Involved in dosage compensation by hypoactivation of X chromosome. Located in X chromosome and nuclear chromosome. Part of dosage compensation complex. Is an ortholog of human SMC4 (structural maintenance of chromosomes 4).
Involved in meiotic DNA double-strand break formation involved in reciprocal meiotic recombination and meiotic chromosome segregation. Located in condensed chromosome. Expressed in gonad.
Enables RNA strand annealing activity; identical protein binding activity; and molecular condensate scaffold activity. Involved in several processes, including masculinization of hermaphroditic germ-line; positive regulation of embryonic development; and positive regulation of fertilization. Located in P granule. Expressed in germ line. Human ortholog(s) of this gene implicated in colorectal cancer; hepatocellular carcinoma; and syndromic X-linked intellectual disability. Is an ortholog of human DDX3X (DEAD-box helicase 3 X-linked) and DDX3Y (DEAD-box helicase 3 Y-linked).
