半岛bd体育手机客户端 说明
一般描述
A peptidyl toxin present in the venom of African tarantula, Hysterocrates gigas that acts as a high affinity, reversible blocker of Cav2.3 (α1E, R-type) channels (IC50= 15-30 nM). The inhibition appears to be voltage-dependent. At lower concentrations it is also shown to block native R-type Ca2+ current in rat neurohypophyseal nerve terminals, however, these effects are not observed at higher concentrations. Does not affect Na+ or K+ currents in several cultured cell types (~ 500 nM).
