WebJul 9, 2012 · Abstract BRAF is a serine/threonine protein kinase activating the MAP kinase/ERK-signaling pathway. About 50 % of melanomas harbors activating BRAF mutations (over 90 % V600E). BRAFV600E has been implicated in different mechanisms underlying melanomagenesis, most of which due to the deregulated activation of the … WebA BRAF mutation is a spontaneous change in the BRAF gene that makes it work incorrectly. A mutation causes the gene to turn on the protein and keep it on, which means certain cells get ongoing signals to keep dividing and no instructions on when to stop. This can lead to development of a tumor.
