WebCeramide-activated protein phosphatases (CAPPs) are a group of enzymes that are activated by the lipid second messenger ceramide. Known CAPPs include members of the protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A) families. CAPPs are a subset of intracellular serine/threonine phosphatases. Each CAPP consists of a catalytic … WebApr 20, 2015 · In the present study, we report the identification of five specific PP5 activators [PP5 small-molecule activators (P5SAs)] that enhance the phosphatase activity up to 8-fold. The compounds are allosteric modulators accelerating efficiently the turnover rate of PP5, but do barely affect substrate binding or the interaction between PP5 and the ...
