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 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
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
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 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
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
Protein (disambiguation) — Protein is a class of biomolecules composed of amino acid chains.Protein may also refer to:Biochemistry* Antifreeze protein, class of polypeptides produced by certain fish, vertebrates, plants, fungi and bacteria * Conjugated protein, protein… … Wikipedia
