HIV-1 p31 also known as HIV-1 integrase is a protein with a molecular mass of approximately 31 kDa. The protein is integral in the viral life cycle and is expressed in cells infected by the HIV-1 virus. It facilitates the insertion of viral DNA into the host cell's genome which is essential for viral replication. HIV-1 p31 functions mainly in the cytoplasm and the nucleus of the host's cells.

Biological function summary

HIV-1 p31 plays a significant role in the viral integration process. As part of the pre-integration complex it assists in the incorporation of the viral DNA into the host genome which allows the virus to hijack the host's machinery for its own replication. This integration is a critical step for the production of new viral particles. The pre-integration complex is a large molecular assembly within which p31 cooperates with other viral proteins like the reverse transcriptase and capsid proteins.

Pathways

HIV-1 p31 is actively involved in the viral replication pathway and the integration of viral DNA. This protein also interacts with other proteins such as host cell factors that facilitate nuclear import of the pre-integration complex. In the context of the integration process p31 plays a significant role alongside the reverse transcriptase and protease enzymes making it a target for antiretroviral drugs aimed at disrupting the HIV-1 life cycle.

HIV-1 p31 is intrinsically connected with HIV/AIDS. The integration function of p31 makes it an attractive target for therapeutic interventions as inhibiting its action can block the viral replication process. Additionally the protein is linked through the disease pathway to other viral proteins such as reverse transcriptase and protease which are also targets for antiretroviral therapy. By targeting these key proteins treatments can effectively manage the progression of HIV infection.
