Wrapping BCR-ABL: it's in the bag.

ABSTRACT

Leukemia, with its origin in a specific genetic abnormality, will only arise if the cell properly folds and processes the oncogenic protein encoded by the mutant gene. In this issue of Blood, Tsukahara and Maru describe a set of proteins that control the processing of the nascent BCR-ABL oncoprotein, providing new avenues for potential therapeutic intervention in chronic myelogenous leukemia (CML).
