High-energy inositol pyrophosphates, such as IP(7) (diphosphoinositol pentakisphosphate), can directly donate a beta-phosphate to a prephosphorylated serine residue generating pyrophosphorylated proteins. Here, we show that the beta subunit of AP-3, a
clathrin-associated protein
complex required for HIV-1 release, is a target of IP(7)-mediated pyrophosphorylation. We have identified Kif3A, a motor protein of the
kinesin
superfamily, as an AP3B1-binding partner and demonstrate that Kif3A, like the AP-3 complex, is involved in an intracellular process required for HIV-1 Gag release. Importantly, IP(7)-mediated pyrophosphorylation of AP3B1 modulates the interaction with Kif3A and, as a consequence, affects the release of HIV-1 virus-like particles. This study identifies a cellular process that is regulated by IP(7)-mediated pyrophosphorylation.
