FIGURE 1:

The cytosolic C- terminus of AQP1 has two CAII binding motifs. Examination of the human AQP1 amino acid sequence identified two consensus carbonic anhydrase binding (CAB) sites in the cytosolic C-terminus. (A) Sequence alignment of the CABs found in AQP1 genes in the indicated species. CAB1 is depicted in blue and CABII in red throughout. (B) Comparison of the same region of the other aquaporins does not reveal this motif.
