  • 产品描述：

    The recombinant Naja kaouthia Alpha-CT protein is encoded by the gene of Alpha-CT (1-71aa). The gene of Alpha-CT was cloned in a system (E.coli) that supported the expression of Alpha-CT. Modification of Alpha-CT by recombinant DNA technology could lead to the expression of the target protein. The protein was fused with N-terminal 10xHis-GST tag & C-terminal Myc tag in the production. The purity is 85% determined by SDS-PAGE.

    Alpha-cobratoxin is a nicotinic acetylcholine receptor. According to some research, Alpha-cobratoxin may have the following features.
    Alpha-cobratoxin as a possible treatment for multiple sclerosis. Alpha-cobratoxin inhibits the T-type calcium current of dorsal root ganglion neurons through the muscarinic M4 receptor and Go-protein βγ subunit-dependent protein kinase A pathway. Isolation and characterization of high-affinity VHH antibody fragments against alpha-cobratoxin.

  • 功能：
    Monomer: binds with high affinity to muscular (alpha-1-beta-1-gamma-delta/CHRNA1-CHRNB1-CHRNG-CHRND) nAChR (tested on Torpedo californica, Kd=0.2-4.5 nM) and neuronal alpha-7/CHRNA7 nicotinic acetylcholine receptors (Kd=13-105 nM). Also inhibits GABA(A) channels. Heteropentamer targets studied are composed of alpha-1-beta-3-gamma-2 (GABRA1-GABRB3-GABRG2) subunits (IC(50)=236 nM), alpha-1-beta-2-gamma-2 (GABRA1-GABRB2-GABRG2) subunits (IC(50)=469 nM), alpha-2-beta-2-gamma-2 (GABRA2-GABRB2-GABRG2) subunits (IC(50)=485 nM), alpha-5-beta-3-gamma-2 (GABRA5-GABRB3-GABRG2) subunits (IC(50)=635 nM), and alpha-2-beta-3-gamma-2 (GABRA2-GABRB3-GABRG2) subunits (IC(50)=1099 nM) (activated by 10 uM GABA).; Homodimer: binds with high affinity (but lower than the monomeric form) to muscular (IC(50)=9.7 nM) and with low affinity to neuronal alpha-7/CHRNA7 nAChRs (IC(50)=1370 nM). However, it acquires (compared to the monomeric form) the capacity to block alpha-3/beta-2 (CHRNA3/CHRNB2) nAChRs.; Heterodimer with cytotoxin 3 (AC P01446): is slightly more active than the homodimer in inhibiting alpha-7/CHRNA7 nAChR and is considerably more active in blocking the alpha-3-beta-2/CHRNA3-CHRNB2 nAChR.
