Adenosine deaminase acting on RNA1 (ADAR1) was previously reported to affect HIV-1 replication. We report data showing that ADAR1 interacts with the HIV-1 p55 Gag protein, the major structural protein of the immature virus capsid. Furthermore, we found that the endogenous ADAR1 is incorporated into virions purified from the supernatant of primary HIV-1-infected CD4<sup>+</sup> T lymphocytes. Additional experiments demonstrated that the expression of the p55 Gag protein is sufficient for ADAR1 incorporation into virus-like particles (VLPs).Overall, our data originally support the evidence that ADAR1 can be part of the cell protein array uploaded in HIV-1 particles.

Abstract

Adenosine deaminase acting on RNA1 (ADAR1) was previously reported to affect HIV-1 replication. We report data showing that ADAR1 interacts with the HIV-1 p55 Gag protein, the major structural protein of the immature virus capsid. Furthermore, we found that the endogenous ADAR1 is incorporated into virions purified from the supernatant of primary HIV-1-infected CD4+ T lymphocytes. Additional experiments demonstrated that the expression of the p55 Gag protein is sufficient for ADAR1 incorporation into virus-like particles (VLPs).Overall, our data originally support the evidence that ADAR1 can be part of the cell protein array uploaded in HIV-1 particles.
