Programmed cell death 6 interacting protein

AIP1
This gene encodes a protein that functions within the ESCRT pathway in the abscission stage of cytokinesis, in intralumenal endosomal vesicle formation, and in enveloped virus budding. 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. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. Related pseudogenes have been identified on chromosome 15.

Among such viruses, we have been focusing on Sendai virus (SeV) and shown that (i) SeV M functionally and physically interact with a component of the ESCRT complex, Alix/AIP1, although budding of M-VLPs does not seem to be dependent on the pathway; (ii) one of the accessory proteins of SeV, C, also interact with Alix/AIP1, and recruit it to the plasma membrane for efficient budding of M-VLPs; (iii) the C protein regulate balance of viral genome and antigenome RNA synthesis for optimized production of infectious virus particles.
