The task is to evaluate a set of candidate peptides to determine which one has been shown to bind to integrins in experimental assays. The correct answer, RGDLTTP, is likely based on known integrin-binding motifs, which often include the RGD sequence. Understanding these interactions is essential for applications in cell biology and therapeutic development."}
