Stromatoxin 1
Stromatoxin 1 is an inhibitor of Potassium Channel, a peptide which can be isolated from tarantulas. Stromatoxin 1 selectively inhibits K (V) 2.1, K (V) 2.2, K (V) 4.2, and K (V) 2.1/9.3 channels. K (V) 2.1 and K (V) 2.2, but not K (V) 4.2, channel subunits play a key role in opposing both myogenic and neurogenic urinary bladder smooth muscle (UBSM) contractions in rats[1].
