Programmed cell death 6-interacting protein also known as ALIX is a protein that in humans is encoded by the PDCD6IP gene. [5] [6]
This gene encodes a protein thought to participate in programmed cell death. Studies using mouse cells have shown that overexpression of this protein can block apoptosis. In addition, the product of this gene binds to the product of the PDCD6 gene, a protein required for apoptosis, in a calcium-dependent manner. This gene product also binds to endophilins, proteins that regulate membrane shape during endocytosis. Overexpression of this gene product and endophilins results in cytoplasmic vacuolization which may be partly responsible for the protection against cell death. [6]
PDCD6IP protein is part of ESCRT pathway. It participates in the membrane scission of the revers topology budding and participates in multivesicular body formation. [7] It is also vital at the later stages and for successful completion of cytokinesis. [8]
PDCD6IP has been shown to interact with PDCD6. [5] [9] The V domain of PDCD6IP recognises Short linear motif LYPxLxxL and this motif is mimicked by p6 late domain of HIV and related viruses which facilitates viral hijacking of ESCRT pathway and consequential budding of viral particles. [10]
Programmed cell death protein 6 is a protein that in humans is encoded by the PDCD6 gene.
Endophilin-A1 is a protein that in humans is encoded by the SH3GL2 gene.
Charged multivesicular body protein 2b is a protein that in humans is encoded by the CHMP2B gene. It forms part of one of the endosomal sorting complexes required for transport (ESCRT) - specifically ESCRT-III - which are a series of complexes involved in cell membrane remodelling. CHMP2B forms long chains that spiral around the neck of a budding vesicle. Along with the other components of ESCRT-III, CHMP2B constricts the neck of the vesicle just before it is cleaved away from the membrane.

The endosomal sorting complexes required for transport (ESCRT) machinery is made up of cytosolic protein complexes, known as ESCRT-0, ESCRT-I, ESCRT-II, and ESCRT-III. Together with a number of accessory proteins, these ESCRT complexes enable a unique mode of membrane remodeling that results in membranes bending/budding away from the cytoplasm. These ESCRT components have been isolated and studied in a number of organisms including yeast and humans. A eukaryotic signature protein, the machinery is found in all eukaryotes and some archaea.
