Modified integrin I-domain polypeptides stabilized in a desired conformation are also provided, as well as screening assays and therapeutic methods utilizing the modified integrin I-domain polypeptides.Type: GrantFiled: March 15, 2005Date of Patent: March 9, 2010Assignee: The Center for Blood Research, Inc.Inventors: Timothy A. Springer, Motomu Shimaoka, Chafen Lu
