The cell membrane – also called the plasma membrane or cytoplasmic membrane – is among the most fascinating and elegant constructs in the world of biology. The cell is considered the fundamental unit or "building block" of all living things on Earth; your own body has trillions of them, an...

Formation of the Trilaminar Cell Membrane If there are a small number of phospholipids, tails congregate with tails outside, forming a micelle, a sphere with a hydrophillic outside in water and a hyrdophobic interior. If the volume of phospholipids increases, however, membranes form. The cell...
S100A4, a member of the S100 family of Ca2+-binding proteins, modulates the motility of both non-transformed and cancer cells by regulating the localization and stability of cellular protrusions. Biochemical studies have demonstrated that S100A4 binds to
In addition to a nucleus, some of the other important organelles of palisade cells include a cell membrane, a large vacuole, chloroplasts as well as a cell membrane among a few others. Between the cells (palisade cells are generally arranged in a vertical manner to each other beneath the epi...
molecular view of the cell membraneIntrinsic proteins penetrate and bind tightly to the lipid bilayer, which is made up largely of phospholipids and cholesterol and which typically is between 4 and 10 nanometers (nm; 1 nm = 10−9metre) in thickness. Extrinsic proteins are loosely bound to ...
Furin cleavage of the HIV envelope glycoprotein is an essential step for cell entry that enables formation of well-folded, native-like glycosylated trimers, releases constraints on the fusion peptide, and limits enzymatic processing of the N-glycan shield. Here, we show that a cleavage-independent...
