Previous GeneCards Identifiers for SMUG1 Gene
This gene encodes a protein that participates in base excision repair by removing uracil from single- and double-stranded DNA. Many alternatively spliced transcript variants exist for this gene; the full-length nature is known for some but not all of the variants. [provided by RefSeq, Aug 2011]
GeneCards Summary for SMUG1 Gene
SMUG1 (Single-Strand-Selective Monofunctional Uracil-DNA Glycosylase 1) is a Protein Coding gene. Diseases associated with SMUG1 include familial colorectal cancer. Among its related pathways are Chks in Checkpoint Regulation and DNA Repair. GO annotations related to this gene include DNA N-glycosylase activity and single-strand selective uracil DNA N-glycosylase activity.
UniProtKB/Swiss-Prot for SMUG1 Gene
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. The activity is greater toward mismatches (U/G) compared to matches (U/A). Excises uracil (U), 5-formyluracil (fU) and uracil derivatives bearing an oxidized group at C5 [5-hydroxyuracil (hoU) and 5-hydroxymethyluracil (hmU)] in ssDNA and dsDNA, but not analogous cytosine derivatives (5-hydroxycytosine and 5-formylcytosine), nor other oxidized bases. The activity is damage-specific and salt-dependent. The substrate preference is the following: ssDNA > dsDNA (G pair) = dsDNA (A pair) at low salt concentration, and dsDNA (G pair) > dsDNA (A pair) > ssDNA at high salt concentration.
