BACKGROUND: The Nedd2/Ich-1 protein belongs to a growing family of mammalian cysteine proteases similar to interleukin-1 beta converting enzyme (ICE). Because of their similarity to the Cacnorhabditis elegans cell death protein CED-3, the ICE-like proteins are thought to play a key role in the execution of apoptosis. The active form of ICE is a tetramer consisting of two heterodimers (p20 + p10)2 derived from the cleavage of the pro-enzyme. RESULTS: In the present communication we show that the p51 Nedd2 precursor (pro-Nedd2) is also cleaved into p20-like (p19) and p10-like (p12) subunits by extracts prepared from cultured cell lines. Extracts from apoptotic NIH-3T3 cells but not normal grow..
