Recombinant Leiurus quinquestriatus quinquestriatus Beta-insect depressant toxin LqqIT2

Product Type Recombinant Protein
Uniprot No. P19855
Species Leiurus quinquestriatus quinquestriatus (Egyptian scorpion) (Deathstalker scorpion)
Protein Names Recommended name: Beta-insect depressant toxin LqqIT2 Short name= Insect toxin 2
Storage The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Function Depressant insect beta-toxins cause a transient contraction paralysis followed by a slow flaccid paralysis. They bind voltage-independently at site-4 of sodium channels and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. Aside from typical beta-toxin effects, this toxin also affects the inactivation process and ion selectivity of the insect voltage-gated sodium channel. This toxin is active only on insects. Is active on the insect voltage-gated sodium channel para.
Subcellular Location Secreted
Protein Families Long (4 C-C) scorpion toxin superfamily, Sodium channel inhibitor family, Beta subfamily
Tissue Specificity Expressed by the venom gland.
