The KCl-cotransporter KCC2 linked to epilepsy.
In the mature brain, the neurotransmitter GABA can cause a postsynaptic hyperpolarization via activation of chloride permeant GABAA receptor channels. This hyperpolarizing response critically depends on chloride extrusion via the KCl-cotransporter KCC2 [1]. Its knockdown in mice impairs synaptic inhibition by changing the electrochemical potential for chloride and thus increases neuronal excita...
متن کاملThe KCl cotransporter isoform KCC3 can play an important role in cell growth regulation.
The KCl cotransporter (KCC) plays a significant role in the ionic and osmotic homeostasis of many cell types. Four KCC isoforms have been cloned. KCC1 and KCC4 activity is osmolality-sensitive and involved in volume regulation. KCC2, a neuronal-specific isoform, can lower intracellular Cl(-) and is critical for inhibitory GABA responses in the mature central nervous system. KCC3, initially clon...
متن کاملCloning and characterization of KCC3 and KCC4, new members of the cation-chloride cotransporter gene family.
The K+-Cl- cotransporters (KCCs) belong to the gene family of electroneutral cation-chloride cotransporters, which also includes two bumetanide-sensitive Na+-K+-2Cl- cotransporters and a thiazide-sensitive Na+-Cl- cotransporter. We have cloned cDNAs encoding mouse KCC3, human KCC3, and human KCC4, three new members of this gene family. The KCC3 and KCC4 cDNAs predict proteins of 1083 and 1150 a...
متن کاملMotor protein-dependent membrane trafficking of KCl cotransporter-4 is important for cancer cell invasion.
The KCl cotransporter (KCC) is a major determinant of osmotic homeostasis and plays an emerging role in tumor biology. This study stresses the important role of KCC4 in tumor malignant behavior. Real-time reverse transcription-PCR on samples collected by laser microdissection and immunofluorescent stainings with different KCC isoform antibodies indicate that KCC4 is abundant in metastatic cervi...
