Ssm Spooky Toxin TFA, found in Scolopendra mutilans, effectively inhibits the KCNQ (voltage-gated potassium channel family 7) channels. Its IC50 values for Kv7.4, Kv1.3, and Shal channels are 2.8 μM, 5.26 μM, and 0.1-0.3 M, respectively. This toxin suppresses cytokine production by specifically targeting KV1.3 channels in T cells and plays a crucial role in the centipede's circulatory system.
