GsAF-1 | Product ID | L8429-100UG |
| Name | GsAF-1 |
| Molecular formula | C160H245N47O41S7 |
| Description |
A 29 amino-acids peptide with 3 disulfide bridges , synthetic, initially isolated from the venom of the Chilean rose tarantula Grammostola rosea, also known as Grammostola spatulata. |
| Biological activity | GsAF-I inhibits voltage-gated sodium channel isoforms: Nav1.1, Nav1.2, Nav1.3, Nav1.4, Nav1.6 and Nav1.7 with respective IC50 values of 0.4, 0.6, 1.3, 0.3, 1.2 and 0.04 µM. In addition, the toxin blocks the hERG1 isoform with an IC50 value of 4.8 µM. GsAF-I does not inhibit sodium channels Nav1.5/SCN5A, and potassium channels Kv1.1/KCNA1, Kv1.4/KCNA4, Kv11.2/KCNH6, Kv11.3/KCNH7 (IC50>200 µM). |
