KCC2 (D1R2R) Rabbit Monoclonal Antibody #94725

The potassium/chloride cotransporter 2 (KCC2, SLC12A5) is a neuron-specific transport protein responsible for regulating the cotransport of potassium and chloride ions. KCC2 uses the energy of the electrochemical potassium gradient to export chloride ions from cells, therefore maintaining intracellular chloride ion concentrations in mature neurons (1,2). The intracellular concentration of chloride ions determines the neuronal response to the inhibitory neurotransmitter GABA and glycine. As a result, KCC2 can play a critical role in regulating neuronal excitability in mature central nervous system neurons (3-5). Altered KCC2 expression and reduced KCC2 activity can result in an increase in intracellular chloride ion concentrations and subsequent hyperexcitability of neuronal systems. Cases of aberrant KCC2 function are associated with neurological disorders, such as multiple forms of epilepsy, neuropathic pain, and schizophrenia (6-10).
