Disease

[OGG1_HUMAN] Defects in OGG1 may be a cause of renal cell carcinoma (RCC) [MIM:144700]. It is a heterogeneous group of sporadic or hereditary carcinoma derived from cells of the proximal renal tubular epithelium. It is subclassified into clear cell renal carcinoma (non-papillary carcinoma), papillary renal cell carcinoma, chromophobe renal cell carcinoma, collecting duct carcinoma with medullary carcinoma of the kidney, and unclassified renal cell carcinoma.

Function

[OGG1_HUMAN] DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N-methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta-lyase activity that nicks DNA 3' to the lesion.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

DNA glycosylase/lyases initiate the repair of damaged nucleobases in the genome by catalyzing excision of aberrant nucleobases and nicking of the lesion-containing DNA strand. Nearly all of these proteins have the unusual property of remaining tightly bound in vitro to the end products of the reaction cascade. We have taken advantage of this property to crystallize and structurally characterize the end product resulting from complete DNA processing by a catalytically active mutant form of human 8-oxoguanine DNA glycosylase (D268E hOgg1). The resulting structure is consistent with the currently accepted catalytic mechanism for the protein. Unexpectedly, however, soaking of a nucleobase analog into the crystals results in religation of the DNA backbone in situ.
