Analysis of aquaporins from the euryhaline barnacle Balanus improvisus reveals differential expression in response to changes in salinity
Fig 5
Amino acids in the Ar/R constriction site of aquaporins in B. improvisus.
The four amino acids in the Ar/R constriction motif in the Balanus aquaporins were identified based on protein alignments with the human water aquaporin AQP1 and the E. coli aquaglyceroporin Glpf, which have well characterized constriction regions. All human aquaporins are included for comparison. Positions and residues for human AQP1 and E. coli Glpf are indicated at the top. The names of the B. improvisus aquaporins are shown in bold.
