What is the normal function of the RAD50 gene?
The RAD50 gene provides instructions for making a protein that is involved in several critical cellular functions, including the repair of damaged DNA.
The RAD50 protein binds to strands of damaged DNA and holds the broken ends together during the repair process. It interacts with two other proteins, produced from the MRE11A and NBN genes, as part of a larger protein complex. These proteins work together to mend broken strands of DNA, which prevents cells from accumulating genetic damage that can trigger them to divide uncontrollably. By repairing damaged DNA, the MRE11A/RAD50/NBN complex helps maintain the stability of a cell's genetic information.
The MRE11A/RAD50/NBN complex interacts with the protein produced from the ATM gene, which plays an essential role in recognizing broken strands of DNA and coordinating their repair. DNA can be damaged by agents such as toxic chemicals or radiation, and breaks in DNA strands also occur naturally when chromosomes exchange genetic material in preparation for cell division.
