a Schematic structure of NPM1 chimeric proteins found in cancers. NPM1 is represented as in Fig. 2b. b Representation of the localization of wild-type NPM1, NPM1c+ and NPM1-ALK fusion protein in cancer. NPM1c+ (indicated by an asterisk) is cytoplasmic and can form dimers with NPM1 WT, retaining it in the cytoplasm. NPM1-ALK can dimerize and localize to the cytoplasm. Inversely, NPM1-ALK can form heterodimers with NPM1 WT, causing ALK dislocation into the nucleus (arrow). These cells shown both aberrant localization of ALK in the nucleus, and NPM1 in the cytoplasm
