Oncogenic Mutations in B-Raf Some Losses Yield Gains
A study by Wan et al. in this issue of Cell demonstrates that the majority of oncogenic mutations in the B-Raf protein kinase result in increased catalytic activity, through disruption of the autoinhibited state of the kinase domain. Surprisingly, several mutations lead to impaired B-Raf kinase activity, yet these mutants are nevertheless capable of stimulating downstream signaling through tran...
متن کاملMechanism of Activation of the RAF-ERK Signaling Pathway by Oncogenic Mutations of B-RAF
Over 30 mutations of the B-RAF gene associated with human cancers have been identified, the majority of which are located within the kinase domain. Here we show that of 22 B-RAF mutants analyzed, 18 have elevated kinase activity and signal to ERK in vivo. Surprisingly, three mutants have reduced kinase activity towards MEK in vitro but, by activating C-RAF in vivo, signal to ERK in cells. The s...
متن کاملPyrophosphorolysis detects B-RAF mutations in primary uveal melanoma.
PURPOSE Mutations in the genes that control cell proliferation in cutaneous melanoma are generally uncommon in uveal melanoma. Despite the absence of known activating mutations, the RAF-MEK-ERK, or mitogen-activated protein kinase (MAPK), pathway is usually activated in uveal melanoma. An assay with increased potential to identify mutations is now available, and this study was therefore conduct...
متن کاملOncogenic CARD11 mutations in human diffuse large B cell lymphoma.
Diffuse large B cell lymphoma (DLBCL) is the most common form of non-Hodgkin's lymphoma. In the least curable (ABC) subtype of DLBCL, survival of the malignant cells is dependent on constitutive activation of the nuclear factor-kappaB (NF-kappaB) signaling pathway. In normal B cells, antigen receptor-induced NF-kappaB activation requires CARD11, a cytoplasmic scaffolding protein. To determine w...
متن کاملMEK1 mutations confer resistance to MEK and B-RAF inhibition.
Genetic alterations that activate the mitogen-activated protein kinase (MAP kinase) pathway occur commonly in cancer. For example, the majority of melanomas harbor mutations in the BRAF oncogene, which are predicted to confer enhanced sensitivity to pharmacologic MAP kinase inhibition (e.g., RAF or MEK inhibitors). We investigated the clinical relevance of MEK dependency in melanoma by massivel...
