Integrins are proteins that facilitate cell adhesion and are known to bind to specific peptide sequences, often containing the RGD motif. The task is to evaluate the provided peptide candidates to identify which one has been shown to bind or is likely to bind to integrin receptors based on their sequences. The goal is to select the peptide that demonstrates this binding affinity in an in vitro assay."}
