B, D	PF18372	Integrin beta epidermal growth factor like domain 1 (I-EGF_1)	Integrin beta epidermal growth factor like domain 1	This is the I-EGF 1 domain found in several integrin betas such as integrin beta 1-7. Structural analysis reveal an epidermal growth factor-like (I-EGF) domains 1 and 2 [1]. EGF1 lacks one disulfide (C2-C4) relative to the integrin EGF 2, 3, and 4 do ...	This is the I-EGF 1 domain found in several integrin betas such as integrin beta 1-7. Structural analysis reveal an epidermal growth factor-like (I-EGF) domains 1 and 2 [1]. EGF1 lacks one disulfide (C2-C4) relative to the integrin EGF 2, 3, and 4 domains, this allows the C-terminal end of EGF1 to flex remarkably relative to its N-terminal end [14].	Domain

B, D	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

A, C	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
