Protein
Transposon Ty4-P Gag-Pol polyprotein
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Integrase (IN) targets the VLP to the nucleus, where a subparticle preintegration complex (PIC) containing at least integrase and the newly synthesized dsDNA copy of the retrotransposon must transit the nuclear membrane. Once in the nucleus, integrase performs the integration of the dsDNA into the host genome.
