Background Information

Charged multivesicular body protein 1A (CHMP1A), also known as chromatin modifying protein 1A, is a member of the ESCRT-III (endosomal sorting complex required for transport III) complex which is involved in degradation of internalized transmembrane receptor proteins and formation of multivesicular bodies (MVBs) (PMID: 16730941). CHMP1A has both nuclear and cytoplasmic distributions (PMID: 11559748; 11559747). Subcellular localization of CHMP1A seems to vary depending on the cell type (PMID: 23023333). CHMP1A is required for MVBs formation and has a role in stable gene silencing within the nucleus. Besides, the tumor suppressor role of CHMP1A has also been reported (PMID: 18787405; 22261332).
