Recombinant human CHMP1B protein

CHMP1B, also known as charged multivesicular body protein 1b, is probable peripherally associated component of the endosomal sorting required for transport complex III (ESCRT-III) which is involved in multivesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. Recombinant human CHMP1B protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.
