Abstract:
:Caspases are the primary executioners of apoptosis. Although procaspases believe to exist as inactive forms in cells, the detailed regulatory system remains unclear. Here we show that glucocorticoid modulatory element-binding protein 1 (GMEB1) is capable of binding to the prodomain of caspase-2. We found that this molecule inhibits the autoproteolytic activation of procaspase-2 by oligomerization on a chemical compound-dependent system. These findings indicated that GMEB1 might be an endogenous inhibitory protein that selectively interacts with prodomain of caspase-2 to disrupt the autoactivation.
