Focal adhesions are integrin-containing, multi-protein structures that form mechanical links between intracellular actin bundles and the extracellular substrate in many cell types. Focal adhesions are large, dynamic protein complexes through which the cytoskeleton of a cell connects to the ECM. They are limited to clearly defined ranges of the cell, at which the plasma membrane closes to within 15 nm of the ECM substrate. Focal adhesions are in a state of constant flux: pro… Web8 mei 2024 · Anchoring junctions 增强组织中细胞承受机械力的能力 Some integrins mediate cell-cell attachment Cadherins mediate Ca2+ dependent cell-cell adhesion in all animals Cadherins take their name from their dependence on Ca2+ Mutations that inactivate E-cadherin cause the embryo to fall apart and die early in development 全国高校细胞生物 …
