Cell membrane, what is it made up of ? Cell membrane has basically two components: lipids and protein with some amount of carbohydrates. Composition varies in different membranes and that depends on the function. Myelin sheath membrane of nerve cells has high lipid content as its function is to...
Although this membrane serves to protect the cell and its components, it's also surface through which substances are exchanged and information shared with other cells. Like the other cellular membranes, the plasma membrane is made up of lipids and proteins that contribute to the functions and char...

Many membrane proteins function as enzymes, some of them behave as per-meases for facilitated diffusion and a few proteins act as carriers because they actively transport different substances across the membrane. Certain other protein functions as receptors for hormones, recognition centres and a...
Plasma membrane heterotrimeric G proteins transduce extracellular signal from seven transmembrane receptors to downstream effectors. In addition, G proteins and their regulators localize at multiple intracellular sites and play crucial roles in cell division. In model organisms such as Caenorhabditis elegans ...
When plants suffer freeze-induced damage, the plasma membrane is thought to be the primary site of injury because of its central role in regulation of various cellular processes. Cold tolerant species, however, adapt to such freezing conditions by modifying cellular components and functions (cold ...
Structural and functional analysis of glycosphingolipids of Schistosoma mansoni. Glycosphingolipids are ubiquitous membrane components that play important roles in signal transduction events thereby affecting many cellular functions, including modulation of the immune response. Whereas many studies focus on...
Hypomyelination and congenital cataract (HCC), one of these disorders, is caused by mutations in FAM126A, a gene of unknown function3. We show that FAM126A, also known as hyccin, regulates the synthesis of phosphatidylinositol 4-phosphate (PtdIns(4)P), a determinant of plasma membrane ...
Plasma membrane electron transport systems are involved in different cellular functions, including the regulation of growth and development. Two components are essential to understand these systems in plasma membrane: the electron donors... JA González-Reyes,F Córdoba,P Navas - Springer Netherlands 被...
Proteins residing in the plasma membrane have key functions in transport, signal transduction, vesicle trafficking and many other important processes. To better understand these processes it is necessary to reveal the identity of plasma membrane proteins and to monitor modifications and regulation of thei...
