Carnitine 268-277 solute carrier family 22 member 1 Rattus norvegicus 194-238 21359964-11 2011 The OCT1- and OCTN2-expressing cells transported the canonical substrates, 1-methyl-4-phenyl-pyridinium (MPP(+)) and carnitine, respectively. Carnitine 117-126 solute carrier family 22 member 1 Rattus norvegicus 4-8 10825452-7 2000 Carnitine, a zwitterion, interacts with rat OCTN1 with a very low affinity. Carnitine 0-9 solute carrier family 22 member 1 Rattus norvegicus 44-49 10825452-8 2000 However, the transport of carnitine via rat OCTN1 is not evident in the presence or absence of Na(+). Carnitine 26-35 solute carrier family 22 member 1 Rattus norvegicus 44-49
