The co-receptor also recognizes the V1-V2 region of gp120 and the bridging sheet (an antiparallel, 4-stranded β sheet that connects the inner and outer domains of gp120).

The V1-V2 stem can influence "co-receptor usage through its peptide composition as well as by the degree of N-linked glycosylation." Unlike V1-V2 however, the V3 loop is highly variable and thus is the most important determinant of co-receptor specificity.
