Figure 2. Sequence alignment of the transmembrane region of Kv1.1 and Kv1.3.
Annotation highlights sequence conservation between Kv1.1 (residues 325 to 415) and Kv1.3 (residues 350 to 440) sequences (asterisks=conserved); surface-exposed residues that differ between the two sequences are highlighted in yellow, residues in the selectivity filter are highlighted in green, and shaded areas indicate helices.
