TRPV1-Tat is an antagonistic peptide that fuses the TRPV1 (transient receptor potential vanilla subtype 1) of the cell-penetrating peptide Tat. TRPV1-Tat blocks this phosphorylation process by competitively binding to the AKAP79 binding site of TRPV1 , thereby inhibiting the sensitization of TRPV1. TRPV1-Tat can be used in the study of inflammatory pain.
