Palbociclib, a selective inhibitor of cyclin-dependent kinase4/6, blocks HIV-1 reverse transcription through the control of sterile α motif and HD domain-containing protein-1 (SAMHD1) activity

Abstract excerpt

BACKGROUND: Sterile α motif and HD domain-containing protein-1 (SAMHD1) inhibits HIV-1 reverse transcription by decreasing the pool of intracellular deoxynucleotides. SAMHD1 is controlled by cyclin-dependent kinase (CDK)-mediated phosphorylation. However, the exact mechanism of SAMHD1 regulation in primary cells is unclear. We explore the effect of palbociclib, a CDK6 inhibitor, in HIV-1 replication. METHODS:...
