Summary
Predicted to enable DNA N-glycosylase activity; identical protein binding activity; and single-stranded DNA binding activity. Predicted to be involved in base-excision repair. Predicted to be located in cytosol; fibrillar center; and nucleoplasm. Is expressed in several structures, including lower urogenital tract; palatal shelf; reproductive system; retina layer; and urethra epithelium. Orthologous to human SMUG1 (single-strand-selective monofunctional uracil-DNA glycosylase 1). [provided by Alliance of Genome Resources, Nov 2024]

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.
