Glycolipid-dependent and lectin-driven transcytosis in mouse enterocytes

Communications Biology, 2021
Ivashenka et al. report that galectin-3 (Gal3) binding to lactotransferrin drives its transcytosis in enterocytes. Such trafficking is Gal3- and glycosphingolipid-dependent, and Gal3 is found in clathrin-independent carriers.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Membrane trafficking of ATP-sensitive potassium channels [PDF]

, 2005
ATP-sensitive potassium (KATp) channels are known to play a vital role in the regulation of insulin secretion from pancreatic 0-cells. Changes in the ratio of [ATP]/[ADP] within the cell are known to regulate the activity of channels, but very little is ...

Impact of sphingolipids on protein membrane trafficking

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2023
Membrane trafficking is essential to maintain the spatiotemporal control of protein and lipid distribution within membrane systems of eukaryotic cells. To achieve their functional destination proteins are sorted and transported into lipid carriers that construct the secretory and endocytic pathways.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The Sec1/Munc18 protein Vps45 regulates cellular levels of its SNARE binding partners Tlg2 and Snc2 in Saccharomyces cerevisiae [PDF]

, 2012
Intracellular membrane trafficking pathways must be tightly regulated to ensure proper functioning of all eukaryotic cells. Central to membrane trafficking is the formation of specific SNARE (soluble N-ethylmeleimide-sensitive factor attachment protein ...

Membrane Trafficking Components in Cytokinesis [PDF]

Cellular Physiology and Biochemistry, 2012
Cytokinesis, the last major step of cell division, is a complex multistage process involving specific rearrangement of cellular cytoskeleton and a flurry of vesicular transport activities at the cell division plane. Vesicular traffic from the exocytic pathway and the endocytic/recycling pathway, operating again after being shut down since prophase, are

CaVβ-subunit dependence of forward and reverse trafficking of CaV1.2 calcium channels

Molecular Brain, 2022
Auxiliary CaVβ subunits interact with the pore forming CaVα1 subunit to promote the plasma membrane expression of high voltage-activated calcium channels and to modulate the biophysical properties of Ca2+ currents. However, the effect of CaVβ subunits on

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
