solute carrier family 9, subfamily A (NHE3, cation proton antiporter 3), member 3; Involved in pH regulation to eliminate acids generated by active metabolism or to counter adverse environmental conditions. Major proton extruding system driven by the inward sodium ion chemical gradient. Plays an important role in signal transduction (834 aa)

cystic fibrosis transmembrane conductance regulator (ATP-binding cassette sub-family C, member 7); Involved in the transport of chloride ions. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the SLC4A7 transporter. Can inhibit the chloride channel activity of ANO1 (1480 aa)

transient receptor potential cation channel, subfamily V, member 6; Calcium selective cation channel probably involved in Ca(2+) uptake in various tissues, including Ca(2+) reabsorption in intestine. The channel is activated by low internal calcium level, probably including intracellular calcium store depletion, and the current exhibits an inward rectification. Inactivation includes both, a rapid Ca(2+)-dependent and a slower Ca(2+)-calmodulin- dependent mechanism, the latter may be regulated by phosphorylation. In vitro, is slowly inhibited by Mg(2+) in a voltage-independent manner. H [...] (725 aa)

solute carrier family 34 (sodium phosphate), member 1; May be involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane. Probably mediates 70-80% of the apical influx (639 aa)

solute carrier family 22 (organic cation/carnitine transporter), member 5; Sodium-ion dependent, high affinity carnitine transporter. Involved in the active cellular uptake of carnitine. Transports one sodium ion with one molecule of carnitine. Also transports organic cations such as tetraethylammonium (TEA) without the involvement of sodium. Also relative uptake activity ratio of carnitine to TEA is 11.3 (557 aa)

PDZ domain containing 2 (2839 aa)

solute carrier family 15 (H+/peptide transporter), member 2; Proton-coupled intake of oligopeptides of 2 to 4 amino acids with a preference for dipeptides (729 aa)

calcium channel, voltage-dependent, L type, alpha 1S subunit; Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1S gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the ’high-voltage activated’ (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, and b [...] (1873 aa)
