    Summary
    Predicted to enable double-stranded DNA binding activity. Predicted to be involved in reciprocal meiotic recombination. Predicted to act upstream of or within DNA recombination and meiotic cell cycle. Predicted to be active in nucleus. Is expressed in branchial arch; central nervous system; embryo; forelimb bud; and somite. Orthologous to human MND1 (meiotic nuclear divisions 1). [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.
