This event has been computationally inferred from an event that has been demonstrated in another species.The inference is based on the homology mapping from PANTHER. Briefly, reactions for which all involved PhysicalEntities (in input, output and catalyst) have a mapped orthologue/paralogue (for complexes at least 75% of components must have a mapping) are inferred to the other species.

SLC12A1 (Simon DB et al, 1996) is kidney-specific whilst SLC12A2 (Payne JA et al, 1995) is ubiquitously expressed. Two Cl- ions are electroneutrally transported into cells with a Na+ ion and a K+ ion.

Use this URL to connect to the web page of this instance in Reactome: http://www.reactome.org/cgi-bin/eventbrowser_st_id?ST_ID=R-GGA-426155.1K+/Cl- cotransport is implicated not only in regulatory volume decrease, but also in transepithelial salt absorption, renal K+ secretion, myocardial K+ loss during ischemia and regulation of neuronal Cl- concentration. Four genes (SLC12A4-7) encode the K+/Cl- cotransporters KCC1-4 respectively. Cotransport of K+ and Cl- is electroneutral with a 1:1 stoichiometry. These cotransporters function as homomultimers or heteromultimers with other K+/Cl- cotransporters. SLC12A4 encodes KCC1 (Gillen CM et al, 1996). KCC1 is ubiquitously expressed, suggesting a housekeeping role in the regulation of cell volume. SLC12A5 encodes KCC2 (Song L et al, 2002). KCC2's expression is restricted to neurons in the CNS and retina. It is thought KCC2 is important for Cl- homeostasis in neurons. SLC12A6 encodes KCC3 (Race JE et al, 1999; Mount DB et al, 1999). KCC3 is highly expressed in heart, brain, spinal cord, kidney, muscle, pancreas and placenta. Defects in SLC12A6 are a cause of agenesis of the corpus callosum with peripheral neuropathy (ACCPN) (Howard HC et al, 2002). SLC12A7 encodes KCC4 (Mount DB et al, 1999) which is widely expressed, especially in the kidney. It is thought to play a role in transepithelial transport of Cl- by the proximal tubule.

Use this URL to connect to the web page of this instance in Reactome: http://www.reactome.org/cgi-bin/eventbrowser_st_id?ST_ID=R-GGA-426117.1The cation-chloride cotransporter family (SLC12 gene family) are membrane proteins that cotranslocate chloride (Cl-) with either Na+, K+, or both cations electroneutrally. The general topology of these proteins feature 12 transmembrane domains flanked by hydrophilic NH2 and COOH-terminal domains. They are secondary transporters and movement of these cations is determined by gradients established by primary transporters such as Na+-K+-ATPase. Cotransporters that use Na+ as the driving force move Cl- into the cell because Na+ concentration is higher in the extracellular region. Conversely, cotransporters that use K+ as the driving force move Cl- out of the cell because K+ concentration is higher inside the cell. The SLC12 gene family contains nine members, of which seven are clearly characterized genes and two are orphans. They encode cotransporter proteins which are 1) involved in Cl- homeostasis, 2) regulate cell volume, 3) involved in transepithelial ion movement (salt reabsorption in the kidney) and 4) involved in response to neurotransmitters such as GABA. Three different cotransporter subtypes are expressed by the seven characterized genes; one thiazide-sensitive Na+/Cl- cotransporter, two loop diuretic-sensitive Na+, K+/2Cl- cotransporters and four K+/Cl- cotransporters (Gamba G, 2005; Hebert SC et al, 2004).
