Phosphatase activators
WebMay 10, 2011 · Protein tyrosine phosphatases (PTPs) have been implicated in dephosphorylation and inactivation of several animal receptor tyrosine kinases (RTKs), including the epidermal growth factor receptor (EGFR), at the plasma membrane, the endosomes, or the endoplasmic reticulum (ER) ( 5 – 7 ). 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 …
