  2. Peripheral membrane protein - Wikipedia

    en.wikipedia.org/wiki/Peripheral_membrane_protein

    The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure.

  3. Membrane protein - Wikipedia

    en.wikipedia.org/wiki/Membrane_protein

    Although membrane proteins play an important role in all organisms, their purification has historically, and continues to be, a huge challenge for protein scientists. In 2008, 150 unique structures of membrane proteins were available, [14] and by 2019 only 50 human membrane proteins had had their structures elucidated. [13]

  4. Cell membrane - Wikipedia

    en.wikipedia.org/wiki/Cell_membrane

    The basolateral membrane or basolateral cell membrane of a polarized cell is the surface of the plasma membrane that forms its basal and lateral surfaces. [39] It faces outwards, towards the interstitium, and away from the lumen. Basolateral membrane is a compound phrase referring to the terms "basal (base) membrane" and "lateral (side ...

  5. Biological membrane - Wikipedia

    en.wikipedia.org/wiki/Biological_membrane

    Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.

  6. Fences and pickets model of plasma membrane structure

    en.wikipedia.org/wiki/Fences_and_pickets_model...

    The movement of phospholipids, even those located in the outer leaflet of the membrane, is regulated by the actin-based membrane skeleton meshwork.Which is surprising, because the membrane skeleton is located on the cytoplasmic surface of the plasma membrane, and cannot directly interact with the phospholipids located in the outer leaflet of the plasma membrane.

  7. Cell surface receptor - Wikipedia

    en.wikipedia.org/wiki/Cell_surface_receptor

    Each cell membrane can have several kinds of membrane receptors, with varying surface distributions. A single receptor may also be differently distributed at different membrane positions, depending on the sort of membrane and cellular function. Receptors are often clustered on the membrane surface, rather than evenly distributed. [5] [6]

  8. Lipid-anchored protein - Wikipedia

    en.wikipedia.org/wiki/Lipid-anchored_protein

    The lipid-anchored protein can be located on either side of the cell membrane. Thus, the lipid serves to anchor the protein to the cell membrane. [1] [2] They are a type of proteolipids. The lipid groups play a role in protein interaction and can contribute to the function of the protein to which it is attached. [2]

  9. Elasticity of cell membranes - Wikipedia

    en.wikipedia.org/wiki/Elasticity_of_cell_membranes

    In this model, the cell membrane surface is modeled as a two-dimensional fluid-like lipid bilayer where the lipid molecules can move freely. The proteins are partially or fully embedded in the lipid bilayer. Fully embedded proteins are called integral membrane proteins because they traverse the entire thickness of the lipid bilayer. These ...
