Summary: Predicted to enable 3'-flap endonuclease activity. Predicted to contribute to crossover junction DNA endonuclease activity. Predicted to be involved in DNA metabolic process; mitotic intra-S DNA damage checkpoint signaling; and osteoblast proliferation.

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.
