![]() | ![]() Title: Cryo-EM Structures of CRAF/14-3-3 and CRAF/14-3-3/MEK1 Complexes. Authors: Dirk Dedden / Julius Nitsche / Elisabeth V Schneider / Maren Thomsen / Daniel Schwarz / Birgitta Leuthner / Ulrich Grädler / ![]() Abstract: RAF protein kinases are essential effectors in the MAPK pathway and are important cancer drug targets. Structural understanding of RAF activation is so far based on cryo-electron microscopy (cryo-EM) ...RAF protein kinases are essential effectors in the MAPK pathway and are important cancer drug targets. Structural understanding of RAF activation is so far based on cryo-electron microscopy (cryo-EM) and X-ray structures of BRAF in different conformational states as inactive or active complexes with KRAS, 14-3-3 and MEK1. In this study, we have solved the first cryo-EM structures of CRAF/14-3-3 at 3.4 Å resolution and CRAF/14-3-3/MEK1 at 4.2 Å resolution using CRAF kinase domain expressed as constitutively active Y340D/Y341D mutant in insect cells. The overall architecture of our CRAF/14-3-3 and CRAF/14-3-3/MEK1 cryo-EM structures is highly similar to corresponding BRAF structures in complex with 14-3-3 or 14-3-3/MEK1 and represent the activated dimeric RAF conformation. Our CRAF cryo-EM structures provide additional insights into structural understanding of the activated CRAF/14-3-3/MEK1 complex. | |||||||||
