Domain Architecture (Details)
InterPro domains assigned to SynO:
The K-Cl co-transporter (KCC) mediates the coupled movement of K+ and Cl-ions across the plasma membrane of many animal cells. This transport isinvolved in the regulatory volume decrease in response to cell swelling inred blood cells.nd has been proposed to play a role in the vectorialmovement of Cl- across kidney epithelia. The transport process involves onefor one electroneutral movement of K+ together with Cl-.nd.n allknown mammalian cells.he net movement is outward .In neurones.t appears to play a unique role in maintaining lowintracellular Cl-concentration.hich is required for the functioning of Cl-dependent fast synaptic inhibition.ediated by certain neurotransmitters.uch as gamma-aminobutyric acid (GABA) and glycine.Two isoforms of the K-Cl co-transporter have been described.ermed KCC1 andKCC2.ontaining 1085 and 1116 amino acids.espectively. They are bothpredicted to have 12 transmembrane (TM) regions in a central hydrophobicdomain.ogether with hydrophilic N- and C-termini that are likelycytoplasmic. Comparison of their sequences with those of otherion-transporting membrane proteins reveals that they are part of a newsuperfamily of cation-chloride co-transporters.hich includes the Na-Cl andNa-K-2Cl co-transporters. KCC1 is widely expressed in human tissues.hileKCC2 is expressed only in brain neurones.aking it likely that this is theisoform responsible for maintaining low Cl- concentration in neurones .

InterPro domains unassigned to SynO:
Amino acid permeases are integral membrane proteins involved in the transport of amino acids into the cell. A number of such proteins have been found to be evolutionary related . These proteins seem to contain up to 12 transmembrane segments. The best conserved region in this family is located in the second transmembrane segment.This domain is found in a wide variety of permeases.s well as several hypothetical proteins.
  IPR004841:Amino acid permease-associated region
This is a family of K-Cl cotransporters. It includes bumetanide-sensitive sodium-(potassium)-chloride cotransporter.n electrically silent transporter system which is a mediator of sodium and chloride reabsorption. It plays a vital role in the regulation of ionic balance and cell volume. Bumetanide-sensitive sodium-(potassium)-chloride cotransporter belongs to the SLC12A family of transporters.
