Figure 4.

Analysis of concordance of the columns of the multiple alignment of the ppp family. The curves represent the percentage of columns for which a base is present in at least 80% of the sequences. These values are calculated in sliding windows of 50 and 10 bp steps. The minima indicated by A and B represent regions with an insert (A) and rich in A-T sequences (B). In the lower panel, the ellipse indicates the position of the signal peptide and the black box indicates the predicted transmembrane domain. The white box indicates the large deletion in ppp7.
