Breast cancer susceptibility genes 1/2 (BRCA1 and BRCA2) are human such that its protein product either is not made or does not function

E3 ubiquitin-protein ligase that specifically mediates the formation of its modulatory role in the PALB2-dependent loading of BRCA2-RAD51 repair machinery 

S This means that both BRCA1 and BRCA2 genes have the function of repairing DNA, but this function can be impaired if these genes are altered or mutated in any way. This means that you can be at risk of mutated cells and cancer growth through DNA damage. That is why BRCA1 and BRCA2 gene testing has become so essential. Everyone has BRCA1 and BRCA2 genes. The function of the BRCA genes is to repair cell damage and keep breast cells growing normally. But when these genes contain abnormalities or mutations that are passed from generation to generation, the genes don't function normally and breast cancer risk increases.

BRCA1 and BRCA2 are breast cancer gene mutations. When a mutation occurs, the gene doesn’t function properly, DNA errors don’t get repaired, and the risk of The BRCA2 gene encodes a protein that acts as a tumor suppressor. It helps repair damaged DNA and may help regulate cytokinesis (part of cell division) (R). Mutations of this gene are associated with increased risk for cancer and anemia (R). 0 users want this gene increased, 0 users want it decreased BRCA1 and BRCA2 have been described as "breast cancer susceptibility genes" and "breast cancer susceptibility proteins". The predominant allele has a normal, tumor suppressive function whereas high penetrance mutations in these genes cause a loss of tumor suppressive function which correlates with an increased risk of breast cancer. They suggested that the BRCA2 gene may be involved in multiple tumor types and that it may function as a tumor suppressor gene rather than a dominant oncogene.

The BRCA2 protein is involved in repairing damaged DNA. BRCA2 is a human tumor suppressor gene (specifically, a caretaker gene ), found in all humans; its protein, also called by the synonym breast cancer type 2 susceptibility protein, is responsible for repairing DNA. BRCA1 (BReast-CAncer susceptibility gene 1) and BRCA2 are tumor suppressor genes, the mutant phenotypes of which predispose to breast and ovarian cancers. Intensive research has shown that BRCA proteins are involved in a multitude of pivotal cellular processes. In particular, both genes contribute to DNA repair and transcriptional regulation in BRCA1 and BRCA2 are the genes related with breast and ovarian cancer.

Brca2 gene function

2007 Sep 17;97 (6):826-31. Epub 2007 Aug 14. The BRCA2 gene encodes a nuclear phosphoprotein that plays a role in the homologous recombination pathway for double-stranded DNA repair. As a tumor suppressor gene, loss of BRCA2 protein function leads to genomic instability and malignant transformation.

Brca2 gene function

Genetic studies conducted in BRCA1 - and BRCA2 -defective cell lines [ 7 , 9 , 10 ] have further revealed that these tumour suppressor genes are required for maintenance of genome integrity and for normal levels of resistance to DNA damage. BRCA1 and BRCA2 are breast cancer gene mutations.

There are hundreds of mutations identified in these genes. Functional deficiencies due to these mutations impair DNA repair and cause irregularities in the DNA synthesis. BRCA2 is a nuclear protein. Function: BRCA2 has been implicated in maintenance of genomic integrity and in the cellular response to DNA damage.

Hence, both play a critical role in preventing the development. They also maintain the double-strand DNA repair through homologous recombination genes combined with loss of heterozygosity predisposes cells to chromosomal instability and greatly increases the probability of malignant transformation and cancer development.

They also maintain the double-strand DNA repair through homologous recombination genes combined with loss of heterozygosity predisposes cells to chromosomal instability and greatly increases the probability of malignant transformation and cancer development.

The new findings explain how the loss of BRCA1 or BRCA2 function impairs homologous recombination (HR), a normally accurate repair process used to fix DNA breaks, and actually stimulates faulty
