产品详细信息
PEP-161 is a 17 amino acid synthetic peptide whose sequence is derived from mouse KChIP3 protein. The sequence of this peptide is (amino to carboxy terminus): I (30)-K-W-Q-R-P-R-F-T-R-Q-A-L-M-R-C (45)
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and mouse KChIP3, catalog # PA1-928. 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.
靶标信息
Voltage-gated potassium (Kv) channels are key components of the potassium currents in the heart and central nervous system. In the heart, Kv4 channels are involved in the repolarization phase of the action potential. In the brain however, these channels prevent reverse-propagation of action potentials. Found associated with Kv4 channels are a group of calcium-binding proteins termed KChIPs (Kv channel interacting proteins). KChIPs are small molecular weight proteins that bind to the cytoplasmic amino termini of Kv4 alpha-subunits and help to modulate its function. There are currently three known KChIPs; KChIP1 expressed in the brain; KChIP2 expressed in the brain, heart, and lung, and has three isoforms, a, b, and c; and KChIP3, also known as calsenilin and DREAM (downstream regulatory elements (DRE)-antagonist modulator) which is expressed in the brain and testis. KChIP3 has activities beyond the modulation of Kv4 currents. It has been shown that KChIP3 binds to the regulatory DRE and represses transcription from the early-response gene c-fos. Thus, KCHiP3 is the first known calcium-binding protein to function as a DNA-binding transcriptional regulator. KChIP3 is also found associated with the presenilins and is implicated in the mediation of beta-amyloid formation.
