Allostery, a crucial phenomenon for comprehending protein function, interactions, and regulation, involves the transmission of perturbations induced by ligand binding to distant sites within a molecule. Understanding the mechanisms of allostery holds the key to elucidating signal transmission failures and diseases resulting from such disruptions. This study focuses on contributing to this understanding by delving into the intricate dynamics of T-cell receptor and peptide-major histocompatibility complex interactions, which are essential components in the communication network of biological systems. Aiming to reveal the effect of melanoma-associated peptides on allosteric signaling, valuable insights are provided. Molecular dynamics simulations were performed on melanoma-associated-epitope-bound TCR-pMHC complexes, followed by machine learning clustering and network analysis, where this innovative combination facilitated the identification of critical TCR-pMHC contacts that modulate global dynamics and stability, presenting novel insights into the complex dynamics of TCR-pMHC interactions. The results not only contributed molecular understanding to TCR-pMHC interactions but also offered valuable information for the fields of immunotherapy and protein engineering. The findings serve as a guide for future experimental investigations and advance our understanding of the immune response in the context of melanoma.
