Specific regulation of protein phosphatase 2A PR72/B'' subunits by calpain.

Biochemical and biophysical research communications - 4 Sept 2009

Janssens Veerle, Derua Rita, Zwaenepoel Karen, Waelkens Etienne, Goris Jozef

Abstract excerpt

Protein phosphatase 2A (PP2A) represents a family of multimeric serine/threonine phosphatases with pleiotropic roles in signal transduction. We previously described the functional analysis of two Ca(2+)-binding EF-hands in the PR72/B'' class of regulatory PP2A subunits. Now we report partial degradation of PR72/B"alpha2 and PR130/B"alpha1 into a 45-48kDa proteolysis-resistant fragment ('PR45') by the...
