Unique so far among ALK fusion proteins, NPM1-ALK is partially nuclear in localization. Endogenous full length NPM is a nuclear-cytoplasmic shuttling protein that contains a nuclear localization signal; although this domain is not conserved in the NPM-ALK fusion, nuclear localization of NPM-ALK is believed to be facilitated by oligomerization with full-length NPM, which exists in dimeric and pentameric states (Kim et al, 2015; reviewed in Box et al ,2006; Okuwaki, 2007; Ducray et al, 2019). Partial nuclear localization of NPM-ALK allows it to perform roles in transcriptional and epigenetic regulation (reviewed in Ducray et al, 2019).
