There are two mammalian VPS4 isoforms, VPS4A and VPS4B. They belong to the AAA ATPase family. VPS4A is a central regulator for early endosome trafficking [, ]. VSP4 interacts with the ESCRT complex, which directs multiple cellular membrane remodelling events, ranging from the biogenesis of multivesicular bodies and exosomes to the final membrane abscission stage of cytokinesis []. The viral budding via host ESCRT complex can also be regulated by VPS4 [].
This entry represents the MIT domain found in vacuolar protein sorting-associated protein 4.
