Definition
Despite the highly evolved and complex nature of HIV-1, it is still merely an obligate parasite. Thus, the HIV-1 replication cycle is completely dependent on host cellular proteins, lipids, and nucleic acids, herein defined as “cofactors.” HIV-1 advantageously usurps host cellular cofactors to facilitate a number of steps throughout the viral replication cycle. For example, HIV-1 fusion and entry are mediated by the major receptor, CD4, and coreceptors, CCR5 or CXCR4 (Fusion). Upon entry into the cell, HIV-1 reverse transcription is primed by cellular tRNALys3. Integration of the newly synthesized double-stranded viral DNA into the target cell genome is promoted by a cellular integrase-binding protein known as lens epithelium-derived growth factor (LEDGF/p75). The focus of this chapter will be to describe host cellular cofactors required late in the HIV-1 replication cycle, specifically, during viral assembly, budding, and release.
