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

open access: yes, 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.

Heparin inhibits the activity of protein phosphatase‐1 [PDF]

open access: yesFEBS Letters, 1984
Heparin inhibited the dephosphorylation of rabbit skeletal muscle or liver phosphorylase a by protein phosphatase‐1. Other glycosaminoglycans (chondroitin sulfates) and their constituents were found to be without effect. The chromatography of a partially purified phosphatase preparation on heparin—Sepharose CL‐6B resulted in a fraction that did not ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

MKP1 mediates resistance to therapy in HER2-positive breast tumors. [PDF]

open access: yes, 2015
Mitogen-activated protein kinase phosphatase 1 (MKP1 or DUSP1) is an antiapoptotic phosphatase that is overexpressed in many cancers, including breast cancer.

Nuclear Targeting of Protein Phosphatase-1 by HIV-1 Tat Protein [PDF]

open access: yesJournal of Biological Chemistry, 2005
Transcription of human immunodeficiency virus (HIV)-1 genes is activated by HIV-1 Tat protein, which induces phosphorylation of the C-terminal domain of RNA polymerase-II by CDK9/cyclin T1. We previously showed that Tat-induced HIV-1 transcription is regulated by protein phosphatase-1 (PP1).

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Proteomic Analysis of the Spinophilin Interactome in Rodent Striatum Following Psychostimulant Sensitization

open access: yesProteomes, 2018
Glutamatergic projections from the cortex and dopaminergic projections from the substantia nigra or ventral tegmental area synapse on dendritic spines of specific GABAergic medium spiny neurons (MSNs) in the striatum.

Protein phosphatase 5 regulates titin phosphorylation and function at a sarcomere-associated mechanosensor complex in cardiomyocytes. [PDF]

open access: yes, 2018
Serine/threonine protein phosphatase 5 (PP5) is ubiquitously expressed in eukaryotic cells; however, its function in cardiomyocytes is unknown. Under basal conditions, PP5 is autoinhibited, but enzymatic activity rises upon binding of specific factors ...
