The KV11.1 (HERG) channel is a member of the ether-a-go-go (EAG) subfamily of voltage-dependent K+ channels that includes the related proteins KV11.2 and KV11.3 (erg2 and erg3). KV11.1 possess the signature structure of the voltage-dependent K+ channels: six membrane-spanning domains and intracellular N and C termini.The KV11.1 current is characterized by strong inward rectification with slow activation and very rapid inactivation kinetics. The channel is expressed in the brain and heart (where it underlies the IKr current) and has a central role in mediating repolarization of action potentials.Mutations in the KV11.1 channel cause inherited long QT syndrome (LQTS) or abnormalities in the repolarization of the heart that are associated with life-threatening arrhythmias and sudden death. All the identified KV11.1 mutations produce loss of function of the channel via several cellular mechanisms ranging from alterations of gating properties, alterations of channel permeability/selectivity and alterations in intracellular channel trafficking that decreases the number of channels that reach the cell membrane. Lately drug-induced forms of LQTS have been reported for a wide range of non-cardiac drugs including antihistamines, psychoactive agents and antimicrobials. All these drugs potently block the KV11.1 channel as an unintended side effect, prompting regulatory drug agencies to issue recommendations for the testing of new drugs for their potential KV11.1 blocking effect.In addition, KV11.1 expression was found to be upregulated in several tumor cell lines of different histogenesis suggesting that it confers the cells some advantage in cell proliferation. Indeed, in several studies it has been shown that inhibition of the KV11.1 current leads to a decrease in tumor cell proliferation.Abgent is pleased to offer a highly specific antibody directed against an extracellular epitope of human Kv11.1. The Anti-Kv11.1 (HERG) (extracellular) antibody (#AG1102) can be used for western blot, immunoprecipitation, immunohistochemical, immunocytochemical and indirect flow cytometry applications. It has been designed to recognize Kv11.1from rat and human samples. This antibody is a unique and invaluable tool to researchers looking into mutations affecting Kv11.1 trafficking or testing Kv11.1 expression in patients with hematopoietic malignancies among many other potential uses.
