Somatic RIT1 mutations in lung adenocarcinoma. (a) 2D protein structure schematics of RIT1 and KRAS with major protein domains shaded as indicated. Numbers indicate amino-acid positions. Each box represents an independent somatic RIT1 mutation with missense and in-frame indel mutations represented in black or blue, respectively. Arrows indicate two mutational hotspots in KRAS. (b) Predicted protein structure of RIT1. A homology model of RIT1 was generated from an alignment with HRAS (1AGP) using SWISS model and displayed using PYMOL. Amino acids near the switch II domain found mutated in this study are highlighted in yellow, in addition to Q79, which is shown for reference.
