iRhom2 controls the substrate selectivity of stimulated ADAM17-dependent ectodomain shedding

Protein ectodomain shedding by ADAM17 (a disintegrin and metalloprotease 17), a principal regulator of EGF-receptor signaling and TNFα release, is rapidly and posttranslationally activated by a variety of signaling pathways, and yet little is known about the underlying mechanism. Here, we report that inactive rhomboid protein 2 (iRhom2), recently identified as essential for the maturation of ADAM17 in hematopoietic cells, is crucial for the...
