  • Product Detail
  • Company Profile
    Tertiapin-Q, Blocker of Kir Channels Tertiapin has been isolated from the venom of the Honeybee Apis mellifera. Tertiapin-Q is an oxidation-resistant mutant of the wild-type tertiapin where Methionine 13 has been replaced by a Glutamine. Tertiapin-Q blocks the inwardly rectifying Kir1.1 (ROMK1) and Kir3.1/3.4 (GIRK1/GIRK4 also known as IKACh) potassium channels with Kd values of around 2 nM and 8 nM respectively. Tertiapin-Q also inhibits calcium-activated large conductance BK potassium channels (KCa1.1) in a concentration and voltage-dependent manner (IC50 ~ 5 nM), in addition to inhibiting Kir3.1/3.2 (GIRK1/GIRK2) heteromultimer potassium channels with a Kd close to 270 nM. Tertiapin-Q can prevent dose-dependent acetylcholine(ACh)-induced atrioventricular blocks in mammalian hearts, as KCNJ3/KCNJ5 channels (also named I(KACh)), are activated by ACh found in mammalian myocytes. Tertiapin-Q technical information AA sequence: Ala-Leu-Cys3-Asn-Cys5-Asn-Arg-Ile-Ile-Ile-Pro-His-Gln-Cys14-Trp-Lys-Lys-Cys18-Gly-Lys-Lys-NH2 Disulfide bonds: Cys3-Cys14 and Cys5-Cys18 Length (aa): 21 Formula: C106H175N35O24S4 Molecular Weight: 2452 Da Appearance: White lyophilized solid Solubility: water and saline buffer CAS number: [252198-49-5] Source: Synthetic Purity rate: > 97 % http://www.smartox-biotech.com/en/potassium-channel/130-tertiapin-q
