Product Specific Information

PEP-119 is two 14 amino acid synthetic peptides whose sequences are derived from amino acids 90-103 of human Maxi K+ beta protein. The sequence of this peptide is (amino to carboxy terminus): L (90)-Y-H-T-E-D-T-R-D-Q-N-Q-Q-C (103)

This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human Maxi K+ beta, catalog # PA1-924. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~70-fold) for competitive inhibition of antibody-protein binding reactions.

Reconstitute with 0.1 mL of distilled water.

Target Information

Potassium channels are a group of ubiquitously expressed proteins that serve numerous functions in excitable and non-excitable cells. One class of integral membrane potassium channels is the large conductance, calcium-activated potassium channel (Maxi K+). Maxi K+ differs from most other potassium channels in that its activation is controlled by both increases in intracellular calcium and by membrane depolarization. Maxi K+ dual activation is possible because of its structure. The core of the channel, which is similar to other potassium channels, is a Maxi K+ alpha homotetramer that contains both a voltage sensor and an intracellular calcium binding domain. In vascular smooth muscle, an auxiliary beta-subunit is found in a 1:1 stoichiometry. The beta-subunit exhibits its effect on the Maxi K+ channel by effectively decreasing by 5- to 10- fold the concentration of calcium required to keep the pore open. Maxi K+ beta is the target for possible therapeutics because of its role in blood flow and blood pressure regulation.
