TAT-CBD3A6K acetate, is a modified TAT-CBD3 peptide. TAT-CBD3A6K acetate reduces T- and R-type voltage-dependent calcium currents in dorsal root ganglion (DRG) neurons. TAT-CBD3A6K acetate shows anti-nociceptive effects in a model of AIDS-induced peripheral neuropathy by preventing CRMP-2-mediated enhancement of T- and R-type calcium channel function[1][2].
