The plasma membrane is an important compartment that undergoes dynamic changes in composition upon external or internal stimuli. The dynamic subcompartmentation of proteins in ordered low-density (DRM) and disordered high-density (DSM) membrane phases is hypothesized to require interactions with ...

Active membrane transport involves ___. (a) NADH. (b) diffusion. (c) the movement against a concentration gradient. (d) exocytosis. (e) all of the above. What type of transport would be involved when a vesicle fuses with the plasma membrane to secrete material from the cell? a) Endocy...
(a) Describe the structure of the nucleolus. (b) Describe its function. Identify the cell organelle from the given description or function: Fluid-filled space between the plasma membrane and the nuclear membrane where organelles are suspended. ...
Similar roles were then ascribed to the ER–plasma membrane (PM) contact site6,7 and to ER–Golgi contacts8. The discovery of the nuclear vacuolar junction (NVJ) and its role in piecemeal microautophagy of the nucleus9,10, and later the assignment of a role for the ER–PM contact in ...
Based on the CTB, AV, and ST subcellular binding sites, the origins of CTB-, AV- and ST-EV biogenesis are the plasma membrane, cytoplasm, and nucleus, respectively. The differentiation of EV subtypes through membrane lipids underlies the importance of membrane lipids in defining EVs and ...
To quantify cellular traits, we adopted the Cell Painting assay17,18. This multiplexing dye assay uses six stains to capture morphological characteristics for eight cellular compartments: Hoechst 33342 (DNA), wheat germ agglutinin (WGA) (golgi and plasma membrane), concanavalin A (endoplasmic reticulu...
32), the synaptobrevin homologue, the v-SNARE Syb1, a general exocytic vesicle marker22, and Sec6 and Exo70, two subunits of the exocyst, a tethering complex essential for the exocytic vesicles docking at the plasma membrane21, and (iii) the cell wall synthesis machinery, specifically the ...
The GO terms distribution showed that the Secrebiome was mainly composed of Hydrolase activity (18.4%) at Molecular Function (Additional file 8: Fig. S5a), membrane (37%) at Cellular Component (Additional file 8: Fig. S5b); and organic substance metabolic process (21%) at Biological ...
Following four washes with serum-free RPMI-1640 to remove serum, the arrays were sealed with a polycarbonate membrane (pore size of 0.01 µm) for 30 min at 37 °C. Next, arrays were placed in lysis buffer, transcripts hybridized to the mRNA capture beads, and beads recovered from the ...
