Table 7 MIMRs ≥ 33% begin and end at cleavage sites (bold) and sites that have related functions in the translated protein

From: Imperfect DNA mirror repeats in the gag gene of HIV-1 (HXB2) identify key functional domains and coincide with protein structural elements in each of the mature proteins
