Vemurafenib binds BRAF-V600E. 9 / 9
| 9

reach
"The kinase domain of B-raf V600E has strong structural homology with the kinase domains of hRIPK1 and hRIPK3, which explains the similarities between the crystal structure of Nec-1 bound to RIPK1 and the structure of Vemurafenib bound to B-Raf V600E."

reach
"This was also shown to be the case for vemurafenib binding to BRAF V600E."

reach
"It has been shown that vemurafenib binding to BRAF V600E paradoxically activates downstream MAPK signaling via dimerization with non mutant RAF family members and allosteric activation of the non mutant partner [XREF_BIBR]."

reach
"Comparison of this structure to the inactive conformation seen in the structure of vemurafenib bound to BRAF V600E reveals significant differences in the orientation of alphaC."

reach
"Additionally, vemurafenib has been found to induce the trans-activation of WT-BRAF or CRAF through hetero-dimerization between vemurafenib bound BRAF V600E and WT-BRAF or CRAF."

reach
"Comparison of alphaC position in the dabrafenib bound and vemurafenib bound BRAF V600E indicates that vemurafenib induces a greater alphaC shift then dabrafenib."

reach
"Crystal structures of vemurafenib bound to BRAF V600E reveal a solvent exposed chloride at the para-position on the phenyl ring, which we posited would be ideal for linker addition (PDB : 3OG7) 34."

reach
"Based on prior structural data of MEK1-BRAF, vemurafenib bound V600E BRAF, and MEK1-KSR2 and structural alignments of vemurafenib bound V600E BRAF with BRAF or KSR2, we hypothesized a regulatory V600E BRAF- MUT MEK complex where V600E BRAF arginine 662 makes critical contacts with MEK residues in one complex interface (XREF_FIG)."

reach
"PLX4032 binds V600E mutant BRAF with high affinity and inhibits ERK signaling output."
