ASPPs multimerize protein phosphatase 1. [PDF]

PLoS Genetics
Protein Phosphatase 1 (PP1) activity is thought to be spatiotemporally defined by hundreds of different regulatory subunits, but their mechanisms of action are largely unknown.

PTEN protein phosphatase activity regulates metastasis by targeting PKCδ [PDF]

iScience
Summary: PTEN acts as a tumor suppressor through its lipid and protein phosphatase activities. We previously reported that PTEN phosphatase inhibits metastasis independent of its lipid phosphatase.

The Plasmodium falciparum Nuclear Protein Phosphatase NIF4 Is Required for Efficient Merozoite Invasion and Regulates Artemisinin Sensitivity

mBio, 2022
Artemisinin resistance in Plasmodium falciparum has been associated with a mutation in the NLI-interacting factor-like phosphatase PfNIF4, in addition to the mutations in the Kelch13 protein as the major determinant.

Temperature sensing by the calcium-sensing receptor

Frontiers in Physiology, 2023
Whether GPCRs support the sensing of temperature as well as other chemical and physical modalities is not well understood.Introduction: Extracellular Ca2+ concentration (Ca2+o) modulates core body temperature and the firing rates of temperature-sensitive

Truncated PPM1D Prevents Apoptosis in the Murine Thymus and Promotes Ionizing Radiation-Induced Lymphoma

Cells, 2020
Genome integrity is protected by the cell-cycle checkpoints that prevent cell proliferation in the presence of DNA damage and allow time for DNA repair.

Protein phosphatase 5 [PDF]

The International Journal of Biochemistry & Cell Biology, 2008
Protein phosphatase 5 (PP5) is a unique member of the PPP family of serine/threonine phosphatases based on the presence of tetratricopeptide repeat (TPR) domains within its structure. Since its discovery, PP5 has been implicated in wide ranging cellular processes, including MAPK-mediated growth and differentiation, cell cycle arrest and DNA damage ...

Research progress on the relationship between the TOR signaling pathway regulator, epigenetics, and tumor development

Frontiers in Genetics, 2022
Almost all cellular activities depend on protein folding, signaling complex assembly/disassembly, and epigenetic regulation. One of the most important regulatory mechanisms responsible for controlling these cellular processes is dynamic protein ...

Protein Phosphatases in G1 Regulation [PDF]

International Journal of Molecular Sciences, 2020
Eukaryotic cells make the decision to proliferate, to differentiate or to cease dividing during G1, before passage through the restriction point or Start. Keeping cyclin-dependent kinase (CDK) activity low during this period restricts commitment to a new cell cycle and is essential to provide the adequate timeframe for the sensing of environmental ...

Phosphatase specificity principles uncovered by MRBLE:Dephos and global substrate identification

Molecular Systems Biology, 2023
Phosphoprotein phosphatases (PPPs) regulate major signaling pathways, but the determinants of phosphatase specificity are poorly understood. This is because methods to investigate this at scale are lacking.
