Models for multimerization of IN. (Left) IN is represented as a dimer, and a dimer is required for the 3′-OH processing step and half-site integration (4). The location of IN is only an approximation in relationship to the 20-bp marker. (Middle) A tetramer per LTR end is predicted for full-site integration (5, 20). (Right) The model predicts an unknown number of avian IN subunits that forms multimers on the U3 end with a predicted tetramer on the U5 end.
