Functional characterisation of a predicted chloroplastic plant protein phosphatase [PDF]

, 2009
The phosphatase AtPTPKISI is involved in the control of starch metabolism in Arabidopsis thaliana leaves at night. The SEX4 (Starch Excess 4) mutants, lacking this predicted phosphatase, have strongly reduced rates of starch metabolism.

Discovery of Protein Phosphatase 2A Substrates

The FASEB Journal, 2018
The protein ser/thr phosphatases (PSPs) dephosphorylate 1000s of key biological targets, making them attractive therapeutic targets. The serine/threonine protein phosphatases 1 and 2B (PP1; PP2B or calcineurin/CN) bind substrates and regulatory proteins using short functional sequences known as Short Linear Motifs (SLiMs).

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Ginsenoside Rd attenuates beta-amyloid-induced tau phosphorylation by altering the functional balance of glycogen synthase kinase 3beta and protein phosphatase 2A

Neurobiology of Disease, 2013
Neurofibrillary tangles are aggregates of hyperphosphorylated tau that are one of the pathological hallmarks of Alzheimer's disease (AD). Tau phosphorylation is regulated by a balance of kinase and phosphatase activities.

Distinct type-2A protein phosphatases activate HMGCoA reductase and acetyl-CoA carboxylase in liver

, 1997
Acetyl-CoA carboxylase and HMGCoA reductase are inactivated by the same AMP-activated protein kinase and are activated by type-2A protein phosphatase.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Identification of a novel protein phosphatase catalytic subunit by cDNA cloning

, 1988
A cDNA encoding a novel protein phosphatase catalytic subunit (protein phosphatase X) has been isolated from a rabbit liver library. It codes for a protein having 45% and 65% amino acid sequence identity, respectively, to the catalytic subunits of ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

NEURONAL FUNCTIONS OF PROTEIN PHOSPHATASE 2A [PDF]

American Journal of Neuroscience, 2013
Reversible protein phosphorylation is a common and important form of protein posttranslational modification which determines the proteins’ activities, substrate specificity and inhibitions or degradations, depending on the specific amino acid residue, or combination of residues, being targeted.
