Phosphatase activators
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 … WebCDC25A is a protein phosphatase that activates the CDK2/Cyclin E complex by removing the inhibitory phosphates from CDK2, promoting the progression of the cell cycle from G1 to S phase. However, in the case of a mutation in CDC25A resulting in constitutive activation, the protein phosphatase would always be active, leading to the continuous ...
