| 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 | |
| PF07965 | Integrin beta tail domain (Integrin_B_tail) | Integrin beta tail domain | This is the beta tail domain of the Integrin protein. Integrins are receptors which are involved in cell-cell and cell-extracellular matrix interactions. | Domain | |
| PF21520 | Integrin alpha-X-like, Ig-like domain 3 (ITGAX-like_Ig_3) | Integrin alpha-X-like, Ig-like domain 3 | This domain is found in Integrin alpha-X from humans (ITGAX) and similar proteins predominantly found in vertebrates. ITGAX is a receptor for fibrinogen. This region composed of an immunoglobulin-like domain [1,3]. | Domain | |
| PF20805 | Integrin alpha Ig-like domain 2 (Integrin_A_Ig_2) | Integrin alpha Ig-like domain 2 | 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 | |
| PF01839 | FG-GAP repeat (FG-GAP) | FG-GAP repeat | - | Repeat | |
| 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 |
