摘要
Disclosed herein are activating mutations in the BRAF gene that promote nevi and melanoma proliferation. These mutations produce an activated form of BRaf, a serine/threonine kinase participant in the Ras/Raf/MEK/ERK MAPK pathway. In one example of the activating BRAF mutations, a 1796 T → A transversion produces a V599E mutated form of B-Raf. This mutated form of B-Raf possesses a tenfold greater basal kinase activity and induces focus formation in NIH3T3 cells 138 times more efficiently than does wild type B-Raf. Methods of diagnosing BRAF mutations in a subject, methods of treating nevi and melanoma in subjects having BRAF mutations, methods of selecting treatments, methods of screening for agents that influence B-Raf activity, and methods of influencing the expression of BRAF or BRAF variants are also described. Nucleotide sequences for use in the described methods are also provided, as are protein-specific binding agents, such as antibodies, that bind specifically to at least one epitope of a B-Raf variant protein preferentially compared to wild type B-Raf.
