2.A.66.1.14
Human MATE1 electroneutral organocation:H antiporter (transports tetraethylammonium, TEA, and cimetidine as well as cisplatin and oxaliplatin) (Yonezawa et al., 2006). MATE1 also exports chloroquine across the luminal membrane (Müller et al., 2011). It has an established 13 TMS topology with the "extra" TMS in an extracellular C-terminal region that is not essential for function (Zhang et al., 2012).  Also exports 1-methyl-4-phenylpyridinium (MPP), N-methylnicotinamide (NMN), metformin, creatinine, guanidine, procainamide, topotecan, estrone sulfate, acyclovir, cimetidine, ganciclovir and the zwitterionic cephalosporin, cephalexin and cephradin (Nigam 2015). Seems to also play a role in the uptake of oxaliplatin (a platinum anticancer agent). Able to transport paraquat (PQ or N,N-dimethyl-4-4'-bipiridinium); a widely used herbicid. Responsible for the secretion of cationic drugs across the brush border membranes (Tanihara et al. 2007).
