Capsid-Dependent Host Factors in HIV-1 Infection.

ABSTRACT: After invasion of a susceptible target cell, HIV-1 completes the early phase of its life cycle upon integration of reverse-transcribed viral DNA into host chromatin. The viral capsid, a conical shell encasing the viral ribonucleoprotein complex, along with its constitutive capsid protein, plays essential roles at virtually every step in the early phase of the viral life cycle. Recent work has begun to reveal how the viral capsid interacts with specific cellular proteins to promote these processes. At the same time, cellular restriction factors target the viral capsid to thwart infection. Comprehensive understanding of capsid-host interactions that promote or impede HIV-1 infection may provide unique insight to exploit for novel therapeutic interventions.
