Mammalian kidney and liver are critical in maintaining physiological ionic environment.
Kidney specializes in removing toxins, drugs, and other organic cations from the blood by an active process called "renal secretion".
Functional studies have identified two distinct categories of organic cation transporters (Octs): a system driven by transmembrane potential difference that governs the influx of cations, whereas the H+-gradient- dependent transport system may mediate the efflux of organic cations.
Several multispecific, potential-sensitive transporters (Oct1-3) and H+-dependent transporters (OctN1-3) have been cloned and characterized from various tissues.
Oct superfamily of proteins share a high degree of sequence homology and display up to 12 transmembrane domains with cytoplasmic N- and C-terminus.
Oct1 (rat/mouse 556aa, ~95% homology; human 554aa, ~78% homology with rat Oct1) is expressed primarily in the kidney, liver and intestine.
Rat Oct1 has been localized to the basolateral membrane of small intestinal enterocytes, hepatocytes, and S1 segment of the proximal renal tubules.
Oct1 mediated uptake of TEA was pH and Na+-independent and was reduced when membrane potential decreased.
Oct1 also transported NMN, choline, MPP, dopamine, thiamine, noradrenaline, histamine, and spermine but not for putrescine.
