| Abstract | Fibronectin is composed of three repeating structural motifs, of which one is the FnIII module. The three modules form a linear sequence of multiple tandem copies connected by short linker peptides. The secondary structure of the FnIII10 module, which is the only fibronectin module to possess an integrin binding RGD motif, consists of two beta-sheets containing the antiparallel beta-strands ABE and DCFG, respectively, which fold up to form a beta-sandwich. The RGD sequence is located in the loop connecting the beta-strands [ 9990027]. |

Alignments of sequences to 106 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.
