title: Proteolytic processing in development and leukemogenesis.
abstract: There are now numerous examples in the hematopoietic system of genes that are critical for normal hematopoietic development, but when mutated, rearranged, or overexpressed, contribute to leukemogenesis. Two papers in this issue of Cell provide a fascinating twist on this paradigm, and suggest that proteolytic processing of certain of these genes plays an important role both in development and in leukemogenesis. These findings also suggest the possibility that proteases may be therapeutic targets in leukemia.
