 GsAF-II 

 

Blocker of Na_v1.1 / 1.2 / 1.3 / 1.4 / 1.6 / 1.7

鈉離子通道Na_v1.1 / 1.2 / 1.3 / 1.4 / 1.6 / 1.7阻斷劑

 

GsAF-II (also termed Kappa-theraphotoxin-Gr2c, GsAF-2) was originally isolated from the venom of Grammostola rosea spider.  peptide toxin has antinociceptive and antiarrhythmic effects in mammals. The peptide is reported to block the following voltage-gated sodium channels: Na_v1.1, Na_v1.2, Na_v1.3, Na_v1.4, Na_v1.6 and Na_v1.7 with IC₅₀ values of, respectively, 5.7, 12, 24, 4, 6.6 and 1.3 µM. This peptide also blocks hERG1 with an IC₅₀ value of 4.7 µM.
