Compensatory endocytosis retrieves membrane and proteins that are deposited at the plasma membrane during exocytosis. A new study reveals that actin filaments assemble into structures that ...

Exocytosis requires actin depolymerization which is actively counteracted under non-stimulatory conditions,” write the investigators. “Here we show that the actin nucleator, ...

Exocytosis, the fundamental process by which cells secrete hormones such as insulin and other useful biological substances, ... This scaffold contains actin, a protein that forms filaments, ...

The gene discovered in the research couples the exocytosis-regulating protein Sec10 with formin, a protein that regulates the remodeling of the actin cytoskeleton critical to forming cell shapes.

Sep. 28, 2023 — Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament ...

Vesicle‐Associated Actin Assembly by Formins Promotes TGF β ‐Induced ANGPTL4 Trafficking, Secretion and Cell Invasion. Advanced Science , 2023; 2204896 DOI: 10.1002/advs.202204896 Cite This ...

The actin filaments in this so-called HeLa cell are labeled in red/orange, and the movement you see represents the dynamic, ever-changing nature of these filaments within the cell. The GI-SIM ...
