Protein Effect | gain of function |
Gene Variant Descriptions | BRAF V600R (previously reported as V599) lies within the activation segment of the kinase domain of the Braf protein (PMID: 15035987). V600R confers a gain of function to the Braf protein as demonstrated by increased Braf kinase activity, downstream signaling, and the ability to transform cells in culture (PMID: 15035987, PMID: 29533785). |
