Stromatoxin 1是从狼蛛中分离出的肽类钾通道抑制剂,特异性地抑制K(V)2.1、K(V)2.2、K(V)4.2和K(V)2.1/9.3通道。其中,K(V)2.1和K(V)2.2通道亚基对大鼠肌源性和神经源性膀胱平滑肌(UBSM)的收缩起关键调控作用,然而K(V)4.2则不参与此作用。

| 产品描述 | Stromatoxin 1, a peptide isolated from tarantulas, acts as an inhibitor of various potassium channels, including K(V)2.1, K(V)2.2, K(V)4.2, and K(V)2.1/9.3. It selectively targets K(V)2.1 and K(V)2.2 channel subunits, which are crucial in counteracting myogenic and neurogenic contractions of rat urinary bladder smooth muscle (UBSM) [1]. |
