TP53 Regulates Transcription of DNA Repair Genes

Several DNA repair genes contain p53 response elements and their transcription is positively regulated by TP53 (p53). TP53-mediated regulation probably ensures increased protein level of DNA repair genes under genotoxic stress.TP53 directly stimulates transcription of several genes...

Mismatch repair (MMR) directed by MSH2:MSH3 (MutSbeta)

MSH2:MSH3 (MutSbeta) binds unpaired loops of 2 or more nucleotides (Palombo et al. 1996, Genschel et al. 1998). Human cells contain about 6-fold more MSH2:MSH6 than MSH2:MSH3 (MutSbeta) and an imbalance in the ratio can cause a mutator phenotype (Drummond et al. 1997, Marra et al....

Mismatch repair (MMR) directed by MSH2:MSH6 (MutSalpha)

MSH2:MSH6 (MutSalpha) binds single base mismatches and unpaired loops of 1-2 nucleotides (reviewed in Edelbrock et al. 2013). Human cells contain about 6-fold more MSH2:MSH6 than MSH2:MSH3 (MutSbeta), which mediates repair of larger mismatches, and an imbalance in the ratio can cause...

Mismatch Repair

The mismatch repair (MMR) system corrects single base mismatches and small insertion and deletion loops (IDLs) of unpaired bases. MMR is primarily associated with DNA replication and is highly conserved across prokaryotes and eukaryotes. MMR consists of the following basic steps:...

DNA Repair

DNA repair is a phenomenal multi-enzyme, multi-pathway system required to ensure the integrity of the cellular genome. Living organisms are constantly exposed to harmful metabolic by-products, environmental chemicals and radiation that damage their DNA, thus corrupting genetic information....

Meiotic recombination

Meiotic recombination exchanges segments of duplex DNA between chromosomal homologs, generating genetic diversity (reviewed in Handel and Schimenti 2010, Inagaki et al. 2010, Cohen et al. 2006). There are two forms of recombination: non-crossover (NCO) and crossover (CO). In mammals,...

Meiosis

During meiosis the replicated chromosomes of a single diploid cell are segregated into 4 haploid daughter cells by two successive divisions, meiosis I and meiosis II. In meiosis I, the distinguishing event of meiosis, pairs (bivalents) of homologous chromosomes in the form of sister...

Transcriptional Regulation by TP53

The tumor suppressor TP53 (encoded by the gene p53) is a transcription factor. Under stress conditions, it recognizes specific responsive DNA elements and thus regulates the transcription of many genes involved in a variety of cellular processes, such as cellular metabolism, survival,...

Gene Expression

Gene Expression covers the pathways by which genomic DNA is transcribed to yield RNA, the regulation of these transcription processes, and the pathways by which newly-made RNA Transcripts are processed. Most annotation is centered on the generation of messenger RNAs (mRNAs) by regulated...

Fanconi anemia pathway

The Fanconi anemia pathway is required for the efficient repair of damaged DNA, especially interstrand cross-links (ICLs). DNA ICL is directly recognized by FANCM and associated proteins, that recruit the FA core complex. The FA core complex monoubiquitinates FANCD2 and FANCI. The...
