{c}
<KRAS4B> is a <Ras> isoform with a prenylated membrane-targeting region and a <polybasic region>. Contacts between its folded domain and the membrane can alter access to effector-binding surfaces.<Oncogenic and RASopathy-associated K-RAS mutations relieve membrane-dependent occlusion of the effector-binding site by Mohammad T.
