Figure 4From: The integrins of the urochordate Ciona intestinalis provide novel insights into the molecular evolution of the vertebrate integrin familyAlignment of the refined Ciona α chain sequences with representative human orthologues (residues 392-796 based on human α1 integrin chain). Protein domains and conserved motifs are annotated. Levels of sequence conservation are indicated (>50% identical, red; conservative substitutions, blue). Ca2+-binding motifs in β-propeller repeats 5–7 are highlighted.Back to article page
