This peptide is primarily used in research to study cellular signaling pathways, particularly those involving the calcineurin-NFAT (Nuclear Factor of Activated T-cells) pathway. By inhibiting NFAT activation, it helps in understanding immune responses, T-cell activation, and related processes. It is also utilized in studies focused on cardiovascular diseases, as NFAT signaling plays a role in cardiac hypertrophy. Additionally, it aids in exploring potential therapeutic strategies for autoimmune disorders and cancers where NFAT pathways are implicated. Its application extends to investigating calcium signaling in neurons and its impact on neurological conditions.
