The structural requirements for ceramide activation of serine-threonine protein phosphatases
Journal of Lipid Research, 2004 The protein phosphatases1 (PP1) and 2A (PP2A) serve as ceramide-activated protein phosphatases (CAPP). In this study, the structural requirements for interaction between ceramide and CAPP were determined.

PTEN: A master regulator of neuronal structure, function, and plasticity. [PDF]
, 2014 PTEN (phosphatase and tensin homolog on chromosome ten) is a dual protein/lipid phosphatase that dephosphorylates PIP3, thereby inhibiting the AKT/mTOR pathway. This inhibition ultimately decreases protein translation, cell proliferation and cell growth.

Protein tyrosine phosphatase 1 protects human pancreatic cancer from erastin-induced ferroptosis
Asian Journal of Surgery, 2022 Background: Pancreatic ductal adenocarcinoma (PDAC) is a fatal malignancy due to the lack of early detection method, therapeutic drug and target. We noticed that the expression of Protein Tyrosine Phosphatase Mitochondria1(PTPMT1) is upregulated in PDAC.
