The cell cortex, also known as the actin cortex, cortical cytoskeleton or actomyosin cortex, is a specialized layer of cytoplasmic proteins on the inner face of the cell membrane. It functions as a modulator of membrane behavior and cell surface properties.

细胞内大部分微丝都集中在紧贴细胞质膜的细胞质区域，并由微丝结合蛋白交联成凝胶状态的三维网络结构，该区域通常称为细胞皮层（cell cortex）。 皮层内一些微丝还与细胞质膜上的蛋白有链接，使膜蛋白的流动性受到某种程度的限制。

The cell cortex is defined as the peripheral region of the cell where a thin layer of actin forms a meshwork that underlies the entire plasma membrane of the cell and associates with other cellular polymers such as microtubules, intermediate filaments and others.

细胞皮层 （英語： Cell cortex，或译为 細胞皮質），又称 肌动蛋白皮层 （英語： actin cortex，或 actomyosin cortex），是 细胞膜 内面的一层特殊的 细胞质 蛋白。 它的功能是膜行为和细胞表面特性的调节器。 在大多数缺乏 细胞壁 的 真核细胞 中，皮层是一个由F-肌动蛋白丝、 肌凝蛋白 和肌动蛋白结合蛋白组成的富含 肌动蛋白 的网络。 [1][2][3] ^ Salbreux G, Charras G, Paluch E.

In general, the cortex structure and subcellular distribution vary significantly across cell types and physiological states of the cell. This review focuses on our current knowledge of the structure and molecular composition of the cell cortex. Keywords: Cell cortex, actin cytoskeleton, ultrastructure.

The cell cortex is typically defined as a thin layer of actin meshwork that uniformly underlies the plasma membrane of the entire cell. However, this definition applies only to specific cases. In general, the cortex structure and subcellular distribution vary significantly across cell types and physiological states of the cell.

2017年5月22日 · Animal cell shape is controlled primarily by the cell cortex, a thin network of actin filaments, myosin motors and actin-binding proteins that lies directly beneath the plasma membrane 1.

The ability to specialize specific domains of the cell cortex is crucial to the function of almost all cell types. Notable examples include the distinct apical and basolateral membrane domains of epithelial cells, the pre- and post-synaptic membranes of neurons, the leading edges of migrating cells, and the cleavage furrows of dividing cells.

In plants, the cell cortex is a specialized layer of the cytoplasm underlying the plasma-membrane that is composed of a network of microtubules and actin filaments. From: Molecular Plant, 2013
