GsMTx4

GsMTx4 – Ion Channels and Transporters GsMTx4 (GsMTx-4, M-theraphotoxin-Gr1a) has been isolated from the venom of the spider Grammostola rosea. This cationic hydrophobic polypeptide blocks selectively the gating of cation selective channels and mechanosensitive...

GsAF-2

GsAF-2 – Ion Channels and Transporters GsAF-II (also termed Kappa-theraphotoxin-Gr2c, GsAF-2) was originally isolated from the venom of Grammostola rosea spider. GsAF-II peptide toxin has antinociceptive and antiarrhythmic effects in mammals. The peptide is...

GsAF-1

GsAF-1 – Ion Channels and Transporters GsAF-1 (also termed β-theraphotoxin-Gr1b, GsAF-I) was originally isolated from the venom of Grammostola rosea spider. GsAF-I peptide toxin is reported to block the following voltage-gated sodium channel isoforms: Nav1.1,...

GrTx1

GrTx1 – Ion Channels and Transporters GrTx1 toxin is a peptide originally isolated from the venom of the spider Grammostola rosea. GrTx1 preferentially blocks voltage-gated sodium channels. GrTx1 toxin is in the same cluster than other famous sodium channel...

GaTx2

GaTx2 – Ion Channels and Transporters GaTx2 (gating modifier of anion channels 2) was isolated from the venom of Leiurus quinquestriatus hebraeus. GaTx2 is the most potent peptide inhibitor of ClC-2 (CLCN2) chloride channel ever described. Kd value is close to...
