BRAF-V600E activates phosphorylated ERK. 5 / 5
| 5

reach
"Consistent with previous findings, p-ERK activation by the RAS-independent mutation BRAF V600E was not affected by D154Q."

reach
"Inductions of the expression of BRAF V600E, V600K, K601E, L597Q, G469A, G469V, or G464V at levels comparable to those of endogenous BRAF caused significant induction of p-MEK and p-ERK and marked inhibition of RAS-GTP and pCRAF S338."

reach
"Transient expression of BRAF V600E for 48h also increased p-ERK accompanied by increased global histone acetylation, while expression of WT-BRAF did not have such effects (XREF_FIG, middle panel), confirming the specific effect of BRAF V600E on histone acetylation."

reach
"However, AZ138, a V600E mutant BRAF specific inhibitor, paradoxically activated p-ERK in wild type BRAF cell lines (Fig. 1d)."

reach
"The BRAF V600E mutation, which approaches 50% in human melanomas, constitutively activates pERK and contributes to disease progression."
