Inhibition of retroviral replication through modulation of the host cell ubiquitylation

摘要

The present invention relates to methods of inhibiting replication of a retrovirus, such as human immunodeficiency virus (HIV), by inhibiting modulation of ubiquitylation of a host cell substrate protein, such as CEM15 of CD4, where ubiquitylation modulation is mediated by a retroviral protein, such as HIV Vif or Vpu. The invention also relates to screening methods for identifying agents that inhibit viral replication by inhibiting retroviral protein-mediated modulation of host cell ubiquitylation.
