Allowing for the <scene name='90/904312/Arg_1276_open/11'>Arg1276 interaction with Ras in the open conformation</scene> to occur without any steric hindrance as shown in the <scene name='90/904311/Closed_conformation/3'>closed conformation</scene>. In the open state, one of the protomers remains in the closed conformation inaccessible to Ras, while the other protomer is conformationally changed into the open form with Ras bound. It is important to mention, the GRD and Sec14-PH are reoriented away from one another and the GRD site is no longer sterically hindered and clashing with the N-HEAT ARM and is completely accessible for Ras to bind. To undergo the movement to the open conformation, significant conformational changes exist within three separate linkers (L1, L2, L3).<ref name="Bourne"> DOI:10.1038/39470</ref> <ref name="Lupton"> DOI:10.1038/s41594-021-00687-2</ref><ref name="Naschberger"> DOI:10.1038/s41586-021-04024-x</ref>
