FIGURE 2: Integrin-like proteins in fungi share some of the overall structure and motifs with mammalian integrins. Schematic representation of integrin-like INT1 from Candida albicans and Pneumocystis carinii. Indicated are the approximate locations of some motifs – RGD (the integrin binding site), MIDAS (the metal ion-dependent adhesion site), Y (the conserved tyrosine-residue in the C-terminal part), and hatched marking (the transmembrane domain). A prototypical human integrin subunit is shown at the bottom. This figure is from [70] and is published with permission from John Wiley and Sons. Copyright © 2008, American Society for Microbiology.
