GsMTx4. Catalog No.P1205. For research use only. GsMTx4 (Grammostola spatulata mechanotoxin 4, M-theraphotoxin-Gr1a, M-TRTX-Gr1a) is a spider venom peptide that inhibits cationic mechanosensitive channels (MSCs). CAS No. 1209500-46-8.GsMTx-4 is a small peptide obtained from spider venom and has been shown to inhibit MSCs from both the Piezo and TRP families (Gnanasambandam et al., 2017). This inhibitor acts at the interface between the lipids in which the MSC is embedded, thereby reducing the effective magnitude of the mechanical stimulus acting on the MSC …

Yoda1-evoked currents were blocked by Gd 3+ (30 µmol/L) and GsMTx-4 (2.5 µmol/L)—both of which inhibit Piezo1 as well as several other types of ion channels 35,36,38–40 (Figure 4C and 4D).
