The charged multivesicular body proteins or chromatin modifying proteins, commonly designated CHMPs, belong to the vacuolar sorting protein family and function as chromatin-modifying proteins. CHMP1-6 are all components of ESCRT (endosomal sorting complex required for transport) I, II or III complexes. These complexes are crucial for sorting endosomal articles into multivesicular bodies (MVBs), and are also required for the formation of these bodies. CHMP4B (charged multivesicular body protein 4b) is a 224 amino acid protein that interacts with Alix, which results in the redistribution of Alix from the cytoplasm to the perinuclear area. Overexpression of CHMP4B induces accumulation of ubiquinated proteins and inhibits degradation of endocytosed EGF. Defects in the gene encoding CHMP4B can cause posterior polar cataract type 3 (CTPP3), a disease characterized by distinct opacity located at the back of the lens resulting in visual impairment and eventual blindness.
