小细胞分子肌醇六磷酸(IP6)在体外促进HIV-1组装成未成熟的病毒样颗粒已有20年的历史。然而,这种作用背后的分子细节直到最近才被确定,在未成熟的Gag晶格中发现了IP6结合位点。IP6还通过第二个IP6结合位点促进成熟衣壳蛋白(CA)晶格的形成,增强核心稳定性,为逆转录创造有利的环境。IP6还增强了其他逆转录病毒的组装,包括慢病毒和阿尔法逆转录病毒属。这些发现表明IP6可能在整个逆转录病毒科中具有保守的功能。在这里,我们讨论了病毒生命周期中受IP6影响的不同步骤,并详细描述了IP6如何与不同逆转录病毒的未成熟和成熟晶格相互作用。
The small cellular molecule inositol hexakisphosphate (IP6) has been known for ~20 years to promote the in vitro assembly of HIV-1 into immature virus-like particles. However, the molecular details underlying this effect have been determined only recently, with the identification of the IP6 binding site in the immature Gag lattice. IP6 also promotes formation of the mature capsid protein (CA) lattice via a second IP6 binding site, and enhances core stability, creating a favorable environment for reverse transcription. IP6 also enhances assembly of other retroviruses, from both the Lentivirus and the Alpharetrovirus genera. These findings suggest that IP6 may have a conserved function throughout the family Retroviridae. Here, we discuss the different steps in the viral life cycle that are influenced by IP6, and describe in detail how IP6 interacts with the immature and mature lattices of different retroviruses.
