1. An isolated nucleic acid comprising a sequence encoding a polypeptide comprising a fibronectin type III tenth (10Fn3) domain having between about 80 and about 150 amino acids, wherein the 10Fn3 domain binds to an extracellular domain of the human Kinase Insert Domain Receptor (KDR) protein with a dissociation constant (KD) of less than 1×
- 10−
6 M, and wherein the 10Fn3 domain comprises an amino acid sequence that is at least 80% identical to the amino acid sequence of SEQ ID NO;
