Integrin receptors are essential components in the cellular adhesion process and play a critical role in various biological functions including cell signaling, differentiation, and migration. A significant aspect of integrin function is their recognition of specific amino acid sequences in extracellular matrix (ECM) proteins.

The common amino acid sequence recognized by some integrin receptors is RGD, which stands for Arg-Gly-Asp. This sequence is highly conserved and serves as a cell adhesion motif found in many ECM proteins, such as fibronectin, vitronectin, and laminin. When integrin receptors bind to the RGD sequence, it triggers intracellular signaling pathways that promote cell attachment and spreading, making RGD a key element in tissue engineering and regenerative medicine.

The importance of RGD in integrin recognition and cellular interactions exemplifies its utility in designing biomaterials and scaffolds for tissue engineering applications, as it can enhance cell attachment and promote tissue regeneration.
