integrin alpha with A domain 具有A结构域的整联蛋白α An integrin alpha that contains an A domain. A hallmark of this class is the presence of a von Willebrand factor type A domain (Pfam:PF00092) (I-domain) of approximately 200 amino acid residues at the N terminus, which confers divalent cation binding properties. Unlike other integrin alpha proteins, they do not undergo proteolytic cleavage. integrin alpha with I domain 含有A结构域的整联蛋白α。这一类的一个标志是在N末端存在一个约200个氨基酸残基的血管性血友病因子A型结构域（Pfam：PF00092）（I-结构域），其赋予二价阳离子结合性质。不像其他整联α蛋白，他们不经历蛋白水解切割。 带有I域的整合素α integrin alpha 整合素α
