Summary: Predicted to enable sequence-specific DNA binding activity. Involved in DNA methylation involved in gamete generation; gene silencing by RNA; and piRNA metabolic process. Acts upstream of or within several processes, including intrinsic apoptotic signaling pathway in response to DNA damage; male gamete generation; and negative regulation of macromolecule metabolic process. Located in several cellular components, including chromosome; cytoplasmic ribonucleoprotein granule; and perinuclear region of cytoplasm. Is expressed in brain; early conceptus; and genitourinary system. Orthologous to human MAEL (maelstrom spermatogenic transposon silencer). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
