Protein
Solute carrier family 12 member 5
Organism
Rattus norvegicus
Function
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 (PubMed:9930699). Involved in the regulation of dendritic spine formation and maturation (PubMed:22345354).
Similarity
Belongs to the SLC12A transporter family.
