Clathrin protein function
WebAug 19, 2008 · It has been shown that the clathrin fusion protein functions as normally as its endogenous counterpart (10, 28), and that the fluorescent clathrin signal reveals >96% of the clathrin-coated structures . In cells coexpressing epsin 1-Venus and clathrin-ECFP, extensive colocalization was observed between the two fluorescent proteins (Fig. S2A WebClathrin is a protein that plays a major role in the formation of coated vesicles. Clathrin was first isolated and named by Barbara Pearse in 1976. It forms a triskelion shape composed of three clathrin-heavy chains and three light chains. Coat-proteins, like clathrin, are used to build small vesicles in order to transport molecules within cells.
