Integrase function
Integration occurs following production of the double-stranded linear viral DNA by the viral RNA/DNA-dependent DNA polymerase reverse transcriptase. The main function of IN is to insert the viral DNA into the host chromosomal DNA, an essential step for HIV replication. Integration is a "point of no … Se mer Retroviral integrase (IN) is an enzyme produced by a retrovirus (such as HIV) that integrates—forms covalent links between—its genetic information into that of the host cell it infects. Retroviral INs are not to be confused with Se mer HIV integrase is a 32kDa viral protein consisting of three domains- N-terminus, catalytic core domain, and C-terminus, which each have … Se mer • Maertens GN, Engelman AN, Cherepanov P (January 2024).
