(Syn. : Ammodytoxin k2)
AMMODYTOXIN A | Product ID | L8105-1MG |
| Name | AMMODYTOXIN A |
| Molecular formula | C595H915N165O181S16 |
| Description |
A 122 amino-acids protein with 7 disulfide bridges , natural, extracted from Vipera ammodytes snake venom. |
| Biological activity | "ATxA is a snake venom phospholipase A2 (PLA2) that acts as a presynaptic neurotoxin in a triphasic way. ATxA shows an anticoagulant activity by binding with high affinity to activated coagulation factor X (F10) thus inhibiting the formation of the prothrombinase complex (FX/FV) and its activity (IC50 is 20 nM). ATxA was binds intracellular proteins such as calmodulin (CaM) (IC50 is 6 nM), 14-3-3 proteins gamma (YWHAG) and epsilon (YWHAE) (by similarity with AtxC), as well as R25 (by similarity with AtxC), a mitochondrial integral membrane protein found in cerebral cortex. ATxA oes not affect mKv1.1/KCNA1, rKv1.2/KCNA2, mKv1.3/KCNA3, hKv1.5/KCNA5 and mKv3.1/KCNC1 voltage-gated potassium channels." |
