Cleavage of actin by interleukin 1 beta-converting enzyme to reverse DNase I inhibition.
Three of the predominant features of apoptosis are internucleosomal DNA fragmentation, plasma membrane bleb formation, and retraction of cell processes. We demonstrate that actin is a substrate for… Expand

Phosphorylation of the common neurotrophin receptor p75 by p38beta2 kinase affects NF-kappaB and AP-1 activities.
The signaling pathways invoked by ligand binding to the common neurotrophin receptor p75NTR are incompletely understood. Using the yeast two-hybrid system, we identified the mitogen-activated protein… Expand
