Membrane Surface Charge, Phospholipids, and Protein Localization

Abstract:
Cell membranes contain multiple charged lipids that bind proteins dynamically and their spatial organization on the inner/outer membrane leaflet, or in spatially localized areas has considerable biological importance. Myristoylated alanine-rich C kinase substrate (MARCKS) proteins and their roles as electrostatic switches are one example covered. Cell surface charge needs to be monitored and regulated continually and the roles of lipid flippases and scramblases and their electrical regulation also are considered.

The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...
Membrane Lipids
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...
