Purity: > 85% by SDS - PAGE Format: Liquid. In 20 mM Tris-HCl buffer, pH8.0, 10% glycerol, 0.2mM PMSF, 100mM NaCl. CLTB (Clathrin light chain B) belongs to the clathrin light chain family. Clathrin is a protein that plays a major role in the formation of coated vesicles. It forms a triskelion shape composed of three clathrin heavy chains and three light chains. When the triskelia interact they form a polyhedral lattice that surrounds the vesicle. Coat-proteins, like clathrin, are used to build small vesicles in order to safely transport molecules between cells. Clathrin-mediated endocytosis (CME) regulates many cellular physiological processes such as the internalization of growth factors and receptors, entry of pathogens, and synaptic transmission. Recombinant human CLTB protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
