Anti-KCC2/SLC12A5 Antibody Picoband®

Potassium-chloride transporter member 5 is also known by the names: KCC2 (potassium chloride cotransporter 2) for its ionic substrates, and SLC12A5 for its genetic origin from the SLC12A5 gene in humans. It is mapped to 20q13.12. K-Cl cotransporters are proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The protein encoded by this gene is an integral membrane K-Cl cotransporter that can function in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons. Alternative splicing results in two transcript variants encoding different isoforms.

Solute carrier family 12 member 5; Electroneutral potassium-chloride cotransporter 2; K-Cl cotransporter 2; hKCC2; Neuronal K-Cl cotransporter; SLC12A5; KCC2; KIAA1176

Mediates electroneutral potassium-chloride cotransport in mature neurons and is required for neuronal Cl- homeostasis. As major extruder of intracellular chloride, it establishes the low neuronal Cl- levels required for chloride influx after binding of GABA-A and glycine to their receptors, with subsequent hyperpolarization and neuronal inhibition. Involved in the regulation of dendritic spine formation and maturation.
