Molecular weight : 13,574 Da
Buy NOTEXIN from Notechis scutatus Purity: 93%
Biological activity :
Notexin exerts both presynaptic (blocks the release of acetylcholine) and myotoxic activities
Notexin is directly toxic to skeletal muscle (dystrophic effect) upon local application in vivo.
Notexin has also direct nephrotoxicity in experimental mice.
Notexin catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
