Ceramide-activated protein phosphatase

Ceramide-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 subunit which confers phosphatase activity and a regulatory subunit which confers substrate specificity. CAPP involvement has been implicated in glycogen metabolism, apoptotic pathways related to cancer and other cellular pathways related to Alzheimer’s disease.
