Fig. 2. Molecular profiles of melanoma with MAP2K1 in-frame deletion.
a Schematic of functional domains of MAP2K1 (transcript NM_002755), to include number of cases with each in-frame deletion (black bars; length~number of cases) and sites of pathogenic missense mutations (black arrows). The majority of in-frame deletions are present in the catalytic core. b Summary of clinical features and molecular alterations in MAP2K1 in-frame deletion melanomas. NES nuclear export signal, NRR negative regulatory region, ATP ATP binding site, Pro rich proline-rich domain, TERTp TERT promoter.
