WaTx (36-68) (scorpion) (trifluoroacetate salt)

Wasabi receptor toxin (WaTx) (36-68) is a cell-penetrating peptide that corresponds to the mature toxin sequence and is an activator of transient receptor potential ankyrin 1 (TRPA1). It selectively induces currents in HEK293T cells expressing human TRPA1 (EC50 = 15 nM) over cells expressing human TRP melastatin 8 (TRPM8) or human TRP vanilloid 1 (TRPV1) at 100 nM or rat voltage-gated potassium channel 1.2 (Kv1.2), rat Kv2.1, rat Kv3.1, or rat Kv4.3 at 1,000 nM. WaTx induces nocifensive behavior in wild-type but not Trpa1-/- mice.Formal Name: L-alanyl-L-seryl-L-prolyl-L-glutaminyl-L-glutaminyl-L-alanyl-L-lysyl-L-tyrosyl-L-cysteinyl-L-tyrosyl-L-alpha-glutamyl-L-glutaminyl-L-cysteinyl-L-asparaginyl-L-valyl-L-asparaginyl-L-lysyl-L-valyl-L-prolyl-L-phenylalanyl-L-alpha-aspartyl-L-glutaminyl-L-cysteinyl-L-tyrosyl-L-glutaminyl-L-methionyl-L-cysteinyl-L-seryl-L-prolyl-L-leucyl-L-alpha-glutamyl-L-arginyl-L-serine, trifluoroacetate salt.
