Summaries for UNG Gene

Entrez Gene Summary for UNG Gene

  • This gene encodes one of several uracil-DNA glycosylases. One important function of uracil-DNA glycosylases is to prevent mutagenesis by eliminating uracil from DNA molecules by cleaving the N-glycosylic bond and initiating the base-excision repair (BER) pathway. Uracil bases occur from cytosine deamination or misincorporation of dUMP residues. Alternative promoter usage and splicing of this gene leads to two different isoforms: the mitochondrial UNG1 and the nuclear UNG2. The UNG2 term was used as a previous symbol for the CCNO gene (GeneID 10309), which has been confused with this gene, in the literature and some databases. [provided by RefSeq, Nov 2010]

GeneCards Summary for UNG Gene

UNG (Uracil DNA Glycosylase) is a Protein Coding gene. Diseases associated with UNG include Immunodeficiency With Hyper-Igm, Type 5 and Immunodeficiency With Hyper-Igm, Type 4. Among its related pathways are Depyrimidination and Telomere C-strand (Lagging Strand) Synthesis. Gene Ontology (GO) annotations related to this gene include uracil DNA N-glycosylase activity.

UniProtKB/Swiss-Prot for UNG Gene

  • Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine.
