Aminoacidic sequence alignment of LjNIP1 and LjXIP1. Sequence alignments of LjNIP1 and LjXIP1 with the closest protein found with Blast. The amino acid sequences were compared using CLUSTALW software. The two ‘NPA motifs’ are coloured in light grey. The four residues (R1–R4) forming the selectivity filter are shaded in dark grey.
