This gene encodes the enzyme responsible for the excision of 8-oxog uanine, a mutagenic base byproduct which occurs as a result of exposure to reactive oxygen. The action of this enzyme includes lyase activity for chain cleavage. Alternative splicing of the C-terminal region of this gene classifies splice variants into two major groups, type 1 and type 2, depending on the last exon of the sequence. Type 1 alternative splice variants end with exon 7 and type 2 end with exon 8. All variants share the N-terminal region in common, which contains a mitochondrial targeting signal that is essential for mitochondrial localization. Many alternative splice variants for this gene have been described, but the full-length nature for every variant has not been determined. [provided by RefSeq, Aug 2008]
A study in mice demonstrated that exposure to ultraviolet B (UVB) radiation induces damage to self noncoding RNA, including the generation of fragments and altered base-read frequencies, which acts as a damage-associated molecular pattern detected by Toll-like receptor 3 (TLR3) to drive skin inflammation and immunosuppression [Bernard et al.
