Protein phosphatase-1: dual activity regulation by Inhibitor-2

Biochemical Society Transactions, 2020
Inhibitor-2 (I2) ranks amongst the most ancient regulators of protein phosphatase-1 (PP1). It is a small, intrinsically disordered protein that was originally discovered as a potent inhibitor of PP1. However, later investigations also characterized I2 as an activator of PP1 as well as a chaperone for PP1 folding.

Src Homology 2 Domain-Containing Protein Tyrosine Phosphatase Promotes Inflammation and Accelerates Osteoarthritis by Activating β-Catenin

Frontiers in Cell and Developmental Biology, 2021
Osteoarthritis (OA) is a chronic articular disease characterized by cartilage degradation, subchondral bone remodeling and osteophyte formation. Src homology 2 domain-containing protein tyrosine phosphatase (SHP2) has not been fully investigated in the ...

Manzamenones Inhibit T-Cell Protein Tyrosine Phosphatase

Marine Drugs, 2006
: Manzamenones A~C (1~3) and E~F (5~6), unique oxylipin metabolites isolated from a marine sponge Plakortis sp., have been found to exhibit inhibitory activity against Tcell protein tyrosine phosphatase (TCPTP). The inhibitory activity of 2 and 5 against

A new monoclonal antibody detects downregulation of protein tyrosine phosphatase receptor type γ in chronic myeloid leukemia patients [PDF]

, 2017
Background: Protein tyrosine phosphatase receptor gamma (PTPRG) is a ubiquitously expressed member of the protein tyrosine phosphatase family known to act as a tumor suppressor gene in many different neoplasms with mechanisms of inactivation including ...

H2O2 Inhibits ABA-Signaling Protein Phosphatase HAB1

PLoS ONE, 2014
Due to its ability to be rapidly generated and propagated over long distances, H2O2 is an important second messenger for biotic and abiotic stress signaling in plants. In response to low water potential and high salt concentrations sensed in the roots of plants, the stress hormone abscisic acid (ABA) activates NADPH oxidase to generate H2O2, which is ...

Integration of a Phosphatase Cascade with the MAP Kinase Pathway provides for a Novel Signal Processing Function [PDF]

, 2009
We mathematically modeled the receptor-activated MAP kinase signaling by incorporating the regulation through cellular phosphatases. Activation induced the alignment of a phosphatase cascade in parallel with the MAP kinase pathway.

Phosphotyrosyl-protein phosphatase of TCRC-2 cells.

Journal of Biological Chemistry, 1982
Homogenization of TCRC-2 cells yielded a phosphotyrosyl-protein phosphatase with a specific activity approximately 10-=fold higher in particulate than in soluble fractions. Over 90% of the phosphotyrosyl-protein phosphatase associated with the particles was solubilized with 1.0% Nonidet P-40.

Protein tyrosine phosphatase non-receptor type 2 as the therapeutic target of atherosclerotic diseases: past, present and future

Frontiers in Pharmacology, 2023
Tyrosine-protein phosphatase non-receptor type 2(PTPN2), an important member of the protein tyrosine phosphatase family, can regulate various signaling pathways and biological processes by dephosphorylating receptor protein tyrosine kinases. Accumulating
