Fig. 7.

Sequence alignment of switch junctions in SCR2(m,a) and SCR2(m,Ra). Junction sequences from 20 SCR2(m,a)- and 21 SCR2(m,Ra)-derived switched clones are aligned with Sm and Sa sequences. Sequences of upstream (EF-1a promoter side) and downstream (SRa promoter side) junctions are indicated by U and D, respectively, followed by clone numbers. Homologous sequences are highlighted by inverted typeface. Numbers before or after the carets indicate the positions of border nucleotides flanking regions of homology between Sm and Sa, represented as a distance from the promoter-proximal end of S regions.
