Biotinyl-ProTx-II（生物素-原毒素 II）
ProTx-II (Protoxin-II) is a toxin that was originally isolated from Thrixopelma pruriens (Peruvian green velvet tarantula).ProTx-II inhibits both tetrodotoxin-sensitive and tetrodotoxin-resistant channels. ProTx-II inhibits activation by shifting the voltage-dependence of c hannel activation to more positive potentials. ProTx-II potently inhibits all sodium channel subtypes tested (Nav1.2/SCN2A, Nav1.5/SCN5A, Nav1.7/SCN9A, and Nav1.8/SCN10A). It is approximay 15-fold more potent on Nav1.7/SCN9A than on Nav1.5/SCN5A channels and acts on Cav3.1/CACNA1G and interacts more weakly with the related T-Type channel Cav3.2/CACNA1H but potently inhibits the L-type calcium channel Cav1.2/CACNA1C. ProTx-II also binds to phospholipids. ProTx-II, a selective inhibitor of Nav1.7 sodium channels, blocks action potential propagation in nociceptors.
Biotinyl-ProTx-II is a N-ter biotin labeled version of the wild-type ProTx-II useful for a wide range of experimentations.
