CEACAM1 preferentially associates with these regions based on its oligomeric state, as shown by the solid and dashed orange arrows between the two membrane regions that indicate transport. The end state of the activated T cell consists of the clustering of CEACAM1 monomers within lipid rafts. B ...
As photoelectrons for Chlorella cell-derived hydrogen production originate mainly from PSII, which captures solar energy and drives electron transfer in the thylakoid membrane (Fig. 2a), we determined the maximum potential quantum efficiency of PSII in the native and coated algal cells to evaluate th...
Region-specific glycan maps were obtained with ∼120 N-glycan compositions in each region, revealing significant differences in “brain-type” glycans involving high mannose, bisecting, and core and antenna fucosylated species. Additionally, the cell membrane N-glycome of three functional regions of...
Rab proteins are key regulators of membrane trafficking, controlling almost every step of vesicle trafficking including formation, transport and fusion. Approximately 60 Rab proteins are involved in different aspects of membrane regulation in mammalian cells and the functions of many of these proteins ...
As single molecules traverse the cell membrane, which is a curved surface, the motion of divisome proteins like FtsW and FtsI may be underestimated. To address this curvature effect, we calibrated the diameter of the cell (or the septal ring) using the bright-field image.1 In 2D tracking,...
circular and longitudinal smooth muscle layers; and serosa, the outermost layer enveloping the gut tube (Fig.1c). Therefore, the bottom of the crypt where ISCs reside is surrounded by a complex microenvironment composed of diverse types of cells and membrane and capillary structures (Powell et ...
3C and D). The specific gene marker set for cardiomyocyte-0 was enriched in pathways related to fatty acid metabolism, fatty acid oxidation, and lipid oxidation, whereas the gene set for cardiomyocyte-2 was enriched in pathways related to myocardial action potentials, membrane potential regulation,...
membrane voltage changes) and immune responses triggered at the onset of regeneration; cell signaling pathways, especially Wnt and fibroblast growth factor (FGF) signaling; and the role of innervation [1]. Whole-body regeneration is considered to be the ancestral mode of regeneration, and it has ...
Once the KATP channel is closed, the membrane potential is depolarized, action potential triggered, and L-type voltage-dependent Ca2+ channels are opened (Figure 2, step 5b). In response to this rise in intracellular Ca2+, granules fuse with the plasma membrane in a soluble N-ethylmaleimide-...
Cell migration requires sustained forward movement of the plasma membrane at the leading edge. Actin polymerization directly pushes the plasma membrane forward using a combina- tion of actomyosin-based contractility and reversible detachment of membrane from cortical actin cytoskeleton. Dynamic Mts are ...
