A	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
B	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
