The protein phosphatases involved in cellular regulation. Identification of the inhibitor-2 phosphatases in rabbit skeletal muscle [PDF]

European Journal of Biochemistry, 1984
Inhibitor-2, purified by an improved procedure, was used to identify protein phosphatases capable of catalysing its dephosphorylation. The results showed that, under our experimental conditions, protein phosphatases-1, 2A and 2B were the only significant protein phosphatases in rabbit skeletal muscle extracts acting on this substrate.

Role of Plastid Protein Phosphatase TAP38 in LHCII Dephosphorylation and Thylakoid Electron Flow [PDF]

, 2010
Short-term changes in illumination elicit alterations in thylakoid protein phosphorylation and reorganization of the photosynthetic machinery. Phosphorylation of LHCII, the light-harvesting complex of photosystem II, facilitates its relocation to ...

Type One Protein Phosphatase 1 and Its Regulatory Protein Inhibitor 2 Negatively Regulate ABA Signaling.

PLoS Genetics, 2016
The phytohormone abscisic acid (ABA) regulates plant growth, development and responses to biotic and abiotic stresses. The core ABA signaling pathway consists of three major components: ABA receptor (PYR1/PYLs), type 2C Protein Phosphatase (PP2C) and ...

Modeling (not so) rare developmental disorders associated with mutations in the protein-tyrosine phosphatase SHP2

Frontiers in Cell and Developmental Biology, 2022
Src homology region 2 (SH2)-containing protein tyrosine phosphatase 2 (SHP2) is a highly conserved protein tyrosine phosphatase (PTP), which is encoded by PTPN11 and is indispensable during embryonic development.

Protein tyrosine phosphatase TbPTP1:A molecular switch controlling life cycle differentiation in trypanosomes [PDF]

, 2006
Differentiation in African trypanosomes (Trypanosoma brucei) entails passage between a mammalian host, where parasites exist as a proliferative slender form or a G0-arrested stumpy form, and the tsetse fly.

T cell-specific constitutive active SHP2 enhances T cell memory formation and reduces T cell activation

Frontiers in Immunology, 2022
Upon antigen recognition by the T cell receptor (TCR), a complex signaling network orchestrated by protein-tyrosine kinases (PTKs) and protein-tyrosine phosphatases (PTPs) regulates the transmission of the extracellular signal to the nucleus. The role of

The protein tyrosine phosphatase Shp-2 regulates RhoA activity [PDF]

Current Biology, 2000
Remodeling of filamentous actin into distinct arrangements is precisely controlled by members of the Rho family of small GTPases [1]. A well characterized member of this family is RhoA, whose activation results in reorganization of the cytoskeleton into thick actin stress fibers terminating in integrin-rich focal adhesions [2].

Activity of protein phosphatases against initiation factor-2 and elongation factor-2 [PDF]

Biochemical Journal, 1990
The protein phosphatases active against phosphorylase a, elongation factor-2 (EF-2) and the alpha-subunit of initiation factor-2 (eIF-2) [eIF-2(alpha P)] were studied in extracts of rabbit reticulocytes. Swiss-mouse 3T3 fibroblasts and rat hepatocytes, by use of the specific phosphatase inhibitors okadaic acid and inhibitor proteins-1 and -2.

Identification of a protein phosphatase-1/phospholamban complex that is regulated by cAMP-dependent phosphorylation.

PLoS ONE, 2013
In human and experimental heart failure, the activity of the type 1 phosphatase is significantly increased, associated with dephosphorylation of phospholamban, inhibition of the sarco(endo)plasmic reticulum Ca(2+) transport ATPase (SERCA2a) and depressed

Purification and characterization of a protein inhibitor from rat liver that inhibits type 1 protein phosphatase when 3-hydroxy-3-methylglutaryl CoA reductase is the substrate.

Journal of Lipid Research, 1990
A protein inhibitor of HMG-CoA reductase phosphatase activity from rat liver was purified to homogeneity. The protein was purified 4,000-fold with an overall yield of 4%. The purified protein had a molecular mass of 31 kDa.
