| PF08441 | Integrin alpha Ig-like domain 1 (Integrin_A_Ig_1) | Integrin alpha Ig-like domain 1 | This domain is found in integrin alpha and integrin alpha precursors to the C terminus of a number of Pfam:PF01839 repeats and to the N-terminus of the Pfam:PF00357 cytoplasmic region. This region is composed of an immunoglobulin-like domain. | Domain | |
| PF00362 | Integrin beta chain VWA domain (Integrin_beta) | Integrin beta chain VWA domain | Integrins have been found in animals and their homologues have also been found in cyanobacteria, probably due to horizontal gene transfer [1]. This domain corresponds to the integrin beta VWA domain. | Domain | |
