General description

Charged multivesicular body protein 3 (UniProt: Q9Y3E7; also known as Chromatin-modifying protein 3, CHMP3, Neuroendocrine differentiation factor, Vacuolar protein sorting-associated protein 24, hVps24) is encoded by the CHMP3 (also known as CGI149, NEDF, VPS24, CGI-149) gene (Gene ID: 51652) in human. CHMP3 is a component of the endosomal sorting required for transport complex III (ESCRT-III), which is involved in multi-vesicular bodies (MVBs) formation and sorting of endosomal cargo proteins into MVBs. It is widely expressed and its expression is reported in heart, brain, placenta, lung, liver, skeletal muscle, kidney, and pancreas. The acidic C-terminus and the basic N-terminus of CHMP3 are thought to render the protein in a closed, soluble and inactive conformation through an auto-inhibitory intramolecular interaction. The open and active conformation, which enables membrane binding and oligomerization, is achieved by interaction with other cellular binding partners, probably including other ESCRT components. CHMP3 is shown to heteromerize with CHMP2A to form helical tubular structures that expose membrane-interacting sites on the outside. It can also interact with CHMP4A, however, the interaction requires the release of CHMP4A auto-inhibition.
