Part Description

LP212224-2   Serine-threonine protein kinase B-raf
The BRAF gene (B-Raf proto-oncogene, serine/threonine kinase) [HGNC Gene ID:1097] is located on chromosome 7q34. This gene encodes a protein belonging to the raf/mil family of serine/threonine protein kinases. This protein plays a role in regulating the MAP kinase/ERKs signaling pathway, which affects cell division, differentiation, and secretion. Mutations in this gene are associated with cardiofaciocutaneous syndrome, a disease characterized by heart defects, mental retardation and a distinctive facial appearance. Mutations in this gene have also been associated with various cancers, including non-Hodgkin lymphoma, colorectal cancer, malignant melanoma, thyroid carcinoma, non-small cell lung carcinoma, and adenocarcinoma of lung. A pseudogene, which is located on chromosome X, has been identified for this gene. [provided by RefSeq, Jul 2008] [NCBI Gene ID:673] Loss of the BRAF gene can be determined by various techniques, and loss of the protein, which is an indicator of gene mutation or deletion, can be detected by immunohistochemistry techniques.
