ABSTRACT
PDZD8 can bind the capsid proteins of different retroviruses, and transient knockdown of PDZD8 results in a decrease in the efficiency of an early, post-entry event in the retrovirus life cycle. Here we used the CRISPR-CAS9 system to create cell lines in which PDZD8 expression is stably eliminated. The PDZD8-knockout cell lines were infected by human immunodeficiency virus (HIV-1) and murine leukemia virus as efficiently as the parental PDZD8-expressing cells. These results indicate that PDZD8 is not absolutely necessary for HIV-1 infection and diminishes its attractiveness as a potential target for intervention.
