The plasma membrane structure is a lipid bilayer that separates the interior of the cell from the exterior of the cell. Here we describe cell membrane markers that outline the cell boundary for fluorescence imaging. Fluorescent labeled lectins (e.g., wheat germ agglutinin (WGA)) can identify ce...
We determined the cryo-electron microscopy structures of TMEM63B in its open and closed conformations, uncovering a lipid translocation pathway formed in response to changes in the membrane environment. Together, our results identify TMEM63B as a membrane structure-responsive scramblase that controls ...
Plasma Membrane Proteins Embedded within theplasma membraneare several categories of proteins, which serve many cellular functions (Table 1.1). Although theprotein moleculesthemselves are stable, the membrane as a whole is a very dynamic structure, with the configuration of the lipid and protein molecu...
Although this model has undergone several changes over time (since it was proposed in 1972), the fluid mosaic model is the model often used to describe the structure of plasma membrane. According to this model, the plasma membrane is composed of freely moving (in a fluid-like manner) ...

The fluid mosaic model is the common term for the structure of the plasma membrane due to its two dimensional fluid of freely diffusing lipids, which is dotted with proteins. Such proteins either stick to the sheath, or span it to provide a bond from the inside to the outside. The cytosk...
1、细胞生物学基础细胞质膜 Plasma Membrane 细胞为什么要有细胞膜?细胞膜应有的特性是什么? 在漫长的生命进化过程中质膜的出现是一个重要的关键阶段,有了它才确定了细胞为生命的基本单位。质膜的最基本作用:维持细胞内微环境的相对稳定;是细胞与周围环境和细胞与细胞间进行物质交换和能量、信息传递的重要通道。 细胞...

Additionally, we found that MLC1 stabilizes membrane structure of primary astrocytes. The real-time image of shMlc1-transfected primary astrocytes showed dynamic membrane ruffling, which indicated that actin filament reorganization has actively occurred. Instead, the membrane structures are somewhat static ...
