clathrin
clathrin[′klath·rən] (cell and molecular biology) A protein that forms a lattice-shaped coating, through the assembly of subunits called triskelions, on the cytosolic side of membrane regions called coated pits during the initial stages of receptor-mediated endocytosis. Invagination of the pit results in a clathrin-coated vesicle. clathrin
clath·rin (klath'rin), The principal constituent of a polyhedral protein lattice that coats eukaryotic cell membranes (vesicles) and coated pits and appears to be involved in protein secretion and membrane trafficking. This protein also occurs in synaptic vesicles. [L. clathri, lattice] clathrin a protein of eukaryotic cells occurring in indentations of the plasma membrane. These indentations are known as clathrin-coated pits; see RECEPTOR-MEDIATED ENDOCYTOSIS. |
