  • Peripheral membrane protein — Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The… …   Wikipedia

  • peripheral membrane protein — Membrane proteins that are bound to the surface of the membrane and not integrated into the hydrophobic region. Usually soluble and were originally thought to bind to integral proteins by ionic and other weak forces (and could therefore be… …   Dictionary of molecular biology

  • Membrane protein — Crystal structure of Potassium channel KvAP. Calculated hydrocarbon boundaries of the lipid bilayer are indicated by red and blue dots. A membrane protein is a protein molecule that is attached to, or associated with the membrane of a cell or an… …   Wikipedia

  • membrane protein — A protein with regions permanently attached to a membrane (peripheral membrane protein), or inserted into a membrane (integral membrane protein). Insertion into a membrane implies hydrophobic domains in the protein. All transport proteins are… …   Dictionary of molecular biology

  • Integral membrane protein — An Integral Membrane Protein (IMP) is a protein molecule (or assembly of proteins) that is permanently attached to the biological membrane. Such proteins can be separated from the biological membranes only using detergents, nonpolar solvents, or… …   Wikipedia

  • integral membrane protein — A protein that is firmly anchored in a membrane (unlike a peripheral membrane protein). Most is known about the integral proteins of the plasma membrane, where important examples include hormone receptors, ion channels, and transport proteins. An …   Dictionary of molecular biology

  • membrane protein — a protein found in association with the cell membrane, either attached to (peripheral or extrinsic) or inserted in (integral or intrinsic) the membrane; possible roles include enzyme, receptor for a hormone or other molecule, and mediator of… …   Medical dictionary

  • Protein-lipid interaction — is the influence of membrane proteins on the lipid physical state or vice versa. The questions which are relevant to understanding of the structure and function of the membrane are: 1) Do intrinsic membrane proteins bind tightly to lipids, and… …   Wikipedia
