BRCA2

BRCA2 is a human gene that is involved in the repair of chromosomal damage and belongs to a class of genes known as tumor suppressor genes.

Tumor suppressor genes regulate the cycle of cell division by keeping cells from growing and dividing too rapidly or in an uncontrolled way.

Although the structures of the BRCA1 and BRCA2 genes are very different, their functions appear to be similar.

The proteins made by both genes are essential for repairing damaged DNA.

The BRCA2 protein binds to and regulates the protein produced by the RAD51 gene to fix breaks in DNA.
