UniProtKB - Q9YGN6 (SMUG1_XENLA)
Protein
Single-strand selective monofunctional uracil DNA glycosylase
Gene
smug1
Organism
Xenopus laevis (African clawed frog)
Status
Functioni
Recognizes base lesions in the genome and initiates base excision DNA repair. Acts as a monofunctional DNA glycosylase specific for uracil (U) residues in DNA with a preference for single-stranded DNA substrates. Does not exhibit any enzymatic activity towards G/T mismatches.
