Interaction of nucleoredoxin with protein phosphatase 2A

FEBS Letters, 2006
A trimeric protein phosphatase 2A (PP2AT55) composed of the catalytic (PP2Ac), structural (PR65/A), and regulatory (PR55/B) subunits was isolated from rabbit skeletal muscle by thiophosphorylase affinity chromatography, and contained two additional proteins of 54 and 55 kDa, respectively.

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

Protein Phosphatase 2A Mediates Oxidative Stress Induced Apoptosis in Osteoblasts

Mediators of Inflammation, 2015
Osteoporosis is one of the most common bone diseases, which is characterized by a systemic impairment of bone mass and fragility fractures. Age-related oxidative stress is highly associated with impaired osteoblastic dysfunctions and subsequent ...

Effects of Newly Synthesized DCP-LA-Phospholipids on Protein Kinase C and Protein Phosphatases

Cellular Physiology and Biochemistry, 2013
Background/Aims: The linoleic acid derivative DCP-LA selectively activates PKCε and inhibits protein phosphatase 1 (PP1). In the present study, we have newly synthesized phosphatidyl-ethanolamine, -serine, -choline, and -inositol containing DCP-LA at the

Bod1 regulates protein phosphatase 2A at mitotic kinetochores [PDF]

Nature Communications, 2013
Mitotic entry and progression require the activation of several mitotic kinases and the proper regulation and localization of several phosphatases. The activity and localization of each of these enzymes is tightly controlled through a series of specific activators, inhibitors and regulatory subunits.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Protein Phosphatase 2A (PP2A) Regulates EG5 to Control Mitotic Progression

Scientific Reports, 2017
EG5 (KIF11) is a member of the kinesin-like protein family involved in centrosome separation and bipolar spindle formation. When a cell enters mitosis, CDK1 phosphorylates EG5 at Thr926 and promotes EG5 localization on the mitotic spindle which drives ...

The cytoplasmic adaptor protein Caskin mediates Lar signal transduction during Drosophila motor axon guidance [PDF]

, 2011
The multiprotein complexes that receive and transmit axon pathfinding cues during development are essential to circuit generation. Here, we identify and characterize the Drosophila sterile α-motif (SAM) domain-containing protein Caskin, which shares ...
