MicroRNA exporter HuR clears the internalized pathogens by promoting pro‐inflammatory response in infected macrophages

EMBO Molecular Medicine, 2020
HuR is a miRNA derepressor protein that can act as miRNA sponge for specific miRNAs to negate their action on target mRNAs. Here we have identified how HuR, by inducing extracellular vesicles‐mediated export of miRNAs, ensures robust derepression of ...

Determinants for Substrate Specificity of Protein Phosphatase 2A [PDF]

Enzyme Research, 2011
Protein phosphatase 2A- (PP2A-) catalyzed dephosphorylation of target substrate proteins is widespread and critical for cellular function. PP2A is predominantly found as a heterotrimeric complex of a catalytic subunit (C), a scaffolding subunit (A), and one member of 4 families of regulatory subunits (B). Substrate specificity of the holoenzyme complex

The TriTryp Phosphatome: analysis of the protein phosphatase catalytic domains [PDF]

, 2007
Background The genomes of the three parasitic protozoa Trypanosoma cruzi, Trypanosoma brucei and Leishmania major are the main subject of this study. These parasites are responsible for devastating human diseases known as Chagas disease, African sleeping

Memantine Attenuates Alzheimer's Disease-Like Pathology and Cognitive Impairment.

PLoS ONE, 2015
Deficiency of protein phosphatase-2A is a key event in Alzheimer's disease. An endogenous inhibitor of protein phosphatase-2A, inhibitor-1, I1PP2A, which inhibits the phosphatase activity by interacting with its catalytic subunit protein phosphatase-2Ac,

Enhanced insulin sensitivity associated with provision of mono and polyunsaturated fatty acids in skeletal muscle cells involves counter modulation of PP2A [PDF]

, 2014
Aims/HypothesisReduced skeletal muscle insulin sensitivity is a feature associated with sustained exposure to excess saturated fatty acids (SFA), whereas mono and polyunsaturated fatty acids (MUFA and PUFA) not only improve insulin sensitivity but blunt ...

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.

Establishment of a PPP2CA homozygous knockout human embryonic stem cell line via CRISPR/Cas9 system

Stem Cell Research, 2023
Protein phosphatase 2A (PPP2CA) is one of the four main Ser/Thr phosphatase enzymes, which involved in the negative control of cell growth and division. PPP2CA is the main protein phosphatase in the heart, which regulates Ca (2+) through a series of ion ...

Crystallization of the Aα subunit of protein phosphatase 2A [PDF]

Protein Science, 1996
AbstractThe Aα subunit of human protein phosphatase 2A forms crystals in space group P21 with cell dimensions a = 104.0, b = 174.9, c = 168.2 Å, and β angle = 90.2°. At cryogenic temperatures, the crystals diffracted to a resolution limit of ∼ 3.0 Å.
