Cationic amino acid transporter 2

May play a role in classical or alternative activation of macrophages via its role in arginine transport (By similarity) … Functions as a permease involved in the transport of the cationic amino acids (L-arginine, L-lysine, L-ornithine and L-homoarginine); the affinity for its substrates differs between isoforms created by

High affinity choline transporter 1

Functions as an electrogenic, voltage-dependent transporter with variable charge/choline stoichiometry (PubMed:17005849). … SLC5A7/CHT1-mediated choline high-affinity transport in cholinergic neurons is the rate-limiting step for production of ACh, thereby facilitating communication by subsequent action potentials (PubMed:11027560

Excitatory amino acid transporter 3

Can also transport L-cysteine (PubMed:21123949). … Functions as a symporter that transports one amino acid molecule together with two or three Na(+) ions and one proton, in parallel with the counter-transport of one K(+) ion (PubMed:26690923, PubMed:33658209

Organic solute transporter subunit alpha

The OST-alpha/OST-beta complex efficiently transports the major species of bile acids (taurocholate) (PubMed:16317684, PubMed:41606314, PubMed:41606328). … Essential component of the OST-alpha/OST-beta complex, a heterotetramer that acts as the intestinal basolateral transporter responsible for bile acid export from enterocytes into portal blood (PubMed:16317684

Ammonium transporter Rh type C

Ammonium transporter involved in the maintenance of acid-base homeostasis. … Transports ammonium and its related derivative methylammonium across the plasma membrane of epithelial cells likely contributing to renal transepithelial ammonia transport and ammonia metabolism.

Sodium-dependent organic anion transporter

Can also transport other sulfoconjugated molecules such as taurolithocholic acid-3-sulfate and sulfoconjugated pyrenes (PubMed:17491011) … Transports sulfoconjugated steroid hormones from the extracellular compartment into the cytosol in a sodium-dependent manner without hydrolysis (PubMed:17491011, PubMed:23667501, PubMed:24717977, PubMed

Sodium-dependent phosphate transporter 1

Essential for cell proliferation but this function is independent of its phosphate transporter activity (PubMed:19726692) … Sodium-phosphate symporter which preferentially transports the monovalent form of phosphate with a stoichiometry of two sodium ions per phosphate ion (PubMed:11009570, PubMed:16790504, PubMed:17494632,

Sodium-dependent phosphate transporter 2

Sodium-phosphate symporter which preferentially transports the monovalent form of phosphate with a stoichiometry of two sodium ions per phosphate ion (PubMed:12205090, PubMed:15955065, PubMed:16790504,

P-type Ca(2+) transporter

Magnesium transporter MRS2 homolog, mitochondrial

Magnesium transporter that mediates the influx of magnesium into the mitochondrial matrix and regulates magnesium metabolism (PubMed:11401429, PubMed:18384665, PubMed:37543649, PubMed:37938562, PubMed: … Required for normal expression of the mitochondrial respiratory complex I subunits (PubMed:18384665). May play a role in maintaining the inner mitochondrial membrane potential (PubMed:39609651)
