Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

open access: yesCancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

open access: yesThe FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

ALOX15 mediates thrombin‐induced myristoylation, trafficking, and interaction of protease‐activated receptors, leading to platelet activation and hemostasis

open access: yesThe FEBS Journal, EarlyView.
The role of PARs in platelet function is fairly known; however, the underlying mechanisms are not fully understood. We report that thrombin myristoylates PAR4 in mouse platelets and PAR1 and PAR4 in human platelets, facilitating their membrane transport and interaction, leading to PAR3/4 heterodimers in mice and PAR1/4 heterodimers in humans.

Wee1 kinase differentially regulates maize CDKA2;1a and CDKB1;1

open access: yesThe FEBS Journal, EarlyView.
In eukaryotes, Wee1 kinase inhibits the kinase activity of CDK/Cyc complexes through phosphorylation of a conserved residue in the CDK moiety. Wee1 is also present in plants, but has been scarcely studied. We have studied maize Wee1 regulation of CDKA/CycD2;2a or CDKB/CycD2;2a complexes.

Adipocyte‐specific NIK depletion enhances energy metabolism and glucose tolerance in mice

open access: yesThe FEBS Journal, EarlyView.
Obesity is associated with reduced energy expenditure and increased hepatic lipid accumulation. This study reveals that loss of NIK in adipocytes stimulates FGF21‐driven expression of thermogenic genes, including UCP1, and mitochondrial uncoupled respiration.

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization

open access: yesThe FEBS Journal, EarlyView.
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

open access: yesThe FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.
