PROTOXIN-III | Product ID | L8444-100UG |
| Name | PROTOXIN-III |
| Molecular formula | C162H246N52O43S6 |
| Description |
A 33 amino-acids peptide with 3 disulfide bridges , synthetic, initially isolated from the venom of the Peruvian green velvet tarantula Thrixopelma pruriens. |
| Biological activity | ProTx-III (µ-TRTX-Tp1a) inhibits voltage-gated sodium channels without significantly altering the voltage dependence of activation or inactivation. The toxin preferentially inhibits hNav1.7/SCN9A (IC50=2.1 nM) > hNav1.6/SCN8A > hNav1.2/SCN2A > hNav1.1/SCN1A > hNav1.3/SCN3A channels in fluorescent assays. The toxin exhibits analgesic properties by reversing spontaneous pain induced in mice by intraplantar injection with OD1 (AC P84646), a scorpion toxin that potentiates hNav1.7/SCN9A. |
