Mr. Koehler et al., THE 2 HUMAN ORGANIC CATION TRANSPORTER GENES SLC22A1 AND SLC22A2 ARE LOCATED ON CHROMOSOME 6Q26, Cytogenetics and cell genetics, 79(3-4), 1997, pp. 198-200
Polyspecific transporters for organic cations (OCT) belong to a new pr
otein family which also include organic anion transporters. The first
human transporters from this family (OCT1, OCT2) have been recently cl
oned. They translocate small cations like tetraethylammonium, choline
and monoamine neurotransmitters and are involved in hepatic and renal
cation excretion, respectively. We have localized the OCT1 and OCT2 ge
nes (SLC22A1, SLC22A2) on chromosome 6q26.
