PF08441Integrin alpha Ig-like domain 1 (Integrin_A_Ig_1)Integrin alpha Ig-like domain 1This 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
