Evidence for the involvement of lipid rafts localized at the ER-mitochondria associated membranes in autophagosome formation [PDF]

, 2016
Mitochondria-associated membranes (MAMs) are subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. This membrane scrambling between ER and mitochondria appears to play a critical role in the earliest steps of autophagy.

Protein S-palmitoylation in cellular differentiation [PDF]

Biochemical Society Transactions, 2017
Reversible protein S-palmitoylation confers spatiotemporal control of protein function by modulating protein stability, trafficking and activity, as well as protein–protein and membrane–protein associations. Enabled by technological advances, global studies revealed S-palmitoylation to be an important and pervasive posttranslational modification in ...

New biosensors and transgenic mice for multiplex cGMP imaging

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Cardiac sodium channel palmitoylation regulates channel availability and myocyte excitability with implications for arrhythmia generation [PDF]

, 2016
Cardiac voltage-gated sodium channels (Nav1.5) play an essential role in regulating cardiac electric activity by initiating and propagating action potentials in the heart.

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

British Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

Individual Palmitoyl Residues Serve Distinct Roles in H-ras Trafficking, Microlocalization, and Signaling [PDF]

, 2005
H-ras is anchored to the plasma membrane by two palmitoylated cysteine residues, Cys181 and Cys184, operating in concert with a C-terminal S-farnesyl cysteine carboxymethylester. Here we demonstrate that the two palmitates serve distinct biological roles.

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

The 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,

Membrane‐type I metalloproteinase (MT1‐MMP): A key modifier of extracellular matrix microenvironment

The FEBS Journal, EarlyView.
MT1‐MMP: A cellular microenvironment modifier. MT1‐MMP is a major cellular microenvironment modifier, maintaining collagen homeostasis by degrading excess collagen (A), creating a migration path in motile cells such as cancer cells (B), modulating local microenvironmental signaling by cleaving transmembrane receptors (C), and destroying tissue ...
