Genes known as DNA repair genes act like a person who repairs a car. They help fix mistakes in the DNA, or if they can’t fix them, they trigger the cell to die so the mistakes can’t cause any further problems.

When DNA repair is complete, the expression of the SOS genes is repressed, the cell cyle resumes, and the undamaged DNA is segregated to the daughter cells. Damaged DNA also generates signals that block cell-cycle progression in eucaryotes.

In humans, DNA repair genes have been identified largely by studies of individuals suffering from inherited diseases resulting from deficiencies in the ability to repair DNA damage. The most extensively studied of these diseases is xeroderma pigmentosum (XP), a rare genetic disorder that affects approximately one in 250,000 people.

DNA damage, due to environmental factors and normal metabolic processes inside the cell, occurs at a rate of 10,000 to 1,000,000 molecular lesions per cell per day. [2] While this constitutes at most only 0.0003125% of the human genome's approximately 3.2 billion bases, unrepaired lesions in critical genes (such as tumor suppressor genes) can impede a cell's …

These genes function in a diverse set of pathways that involve the recognition and removal of DNA lesions, tolerance to DNA damage, and protection from errors of incorporation made during DNA replication or DNA repair.

Jan 24, 2024 · The review addresses key questions, including the major types of DNA damage, common DNA repair mechanisms, the availability of reliable databases for DNA damage and associated diseases, and the predominant computational research methods for enzymes involved in DNA damage and repair.

At least five major DNA repair pathways—base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), homologous recombination (HR) and non-homologous end joining (NHEJ)—are active throughout different stages of the cell cycle, allowing the cells to repair the DNA damage.

Feb 16, 2001 · Notable features presently include four enzymes that can remove uracil from DNA, seven recombination genes related to RAD51, and many recently discovered DNA polymerases that bypass damage, but only one system to remove the main DNA lesions induced by …

Apr 19, 2015 · Here you will find an update on DNA repair and chromatin remodeling genes with links to functional databases. You can browse the cell cycle expression profiles of periodically expressed genes and DNA repair pathways.
