• Description: Tertiapin Q is a peptide inhibitor, a derivative of tertiapin, from honeybee venom (specifically Apis mellifera). This peptide acts by specifically blocking certain potassium channels, namely Kir1.1 and Kir3.1/3.4. The mode of action involves binding to the outer mouth of the potassium channel pore, effectively inhibiting ion flow through these channels. Tertiapin Q varies from native tertiapin by one amino acid, where a methionine residue is replaced with a glutamine residue. This means that unlike native TPN, TPN(Q) is not air oxidizable.Tertiapin : H-Ala-Leu-Cys-Asn-Cys-Asn-Arg-Ile-Ile-Ile-Pro-His-Met-Cys-Trp-Lys-Lys-Cys-Gly-Lys-Lys-NH2Tertiapin Q: H-Ala-Leu-Cys-Asn-Cys-Asn-Arg-Ile-Ile-Ile-Pro-His-Gln-Cys-Trp-Lys-Lys-Cys-Gly-Lys-Lys-NH2Tertiapin Q is used in electrophysiological research to study the role and regulation of inward-rectifier potassium channels in various physiological and pathological processes. Its specificity and potency make it an invaluable tool in the exploration of renal physiology and cardiac cellular activity, as well as in neuroscience research for understanding neuronal excitability.
