Target

Full Name
Vacuolar Protein Sorting 4 Homolog A
Introduction
VPS4A is a member of the aa aprotein family (ATPases associated with diverse cellular activities), and is the homolog of the yeast Vps4 protein. In humans, two paralogs of the yeast protein have been identified. Functional studies indicate that both human paralogs associate with the endosomal compartments, and are involved in intracellular protein trafficking, similar to Vps4 protein in yeast.

Function
Involved in late steps of the endosomal multivesicular bodies (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, possibly in combination with membrane fission. Redistributes the ESCRT-III components to the cytoplasm for further rounds of MVB sorting. 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. It is required for proper accomplishment of various processes including the regulation of endosome size, primary cilium organization, mitotic spindle organization, chromosome segregation, and nuclear envelope sealing and spindle disassembly during anaphase (PubMed:33186545).
Involved in cytokinesis: retained at the midbody by ZFYVE19/ANCHR and CHMP4C until abscission checkpoint signaling is terminated at late cytokinesis. It is then released following dephosphorylation of CHMP4C, leading to abscission (PubMed:24814515).
VPS4A/B are required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413).
Critical for normal erythroblast cytokinesis and correct erythropoiesis (PubMed:33186543).
(Microbial infection) In conjunction with the ESCRT machinery also appears to function in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses).

Cellular Location
Late endosome membrane
Midbody
Cytoplasm, cytoskeleton, spindle
Membrane-associated in the prevacuolar endosomal compartment. Localizes to the midbody of dividing cells, interaction with ZFYVE19/ANCHR mediates retention at midbody (PubMed:24814515).
Localized in two distinct rings on either side of the Flemming body.
Involvement in disease
CIMDAG syndrome (CIMDAG):
An autosomal dominant syndrome characterized by global developmental delay, severely impaired intellectual development, poor or absent speech, microcephaly, growth retardation, poor motor skills with inability to walk, hypotonia and spasticity, and cataracts. Cerebral and cerebellar atrophy, thin corpus callosum, and delayed myelination are apparent on brain imaging. Affected individuals show hematologic abnormalities mostly consistent with congenital dyserythropoietic anemia.
