Gene Name MATE1
Uniprot ID S47A1_HUMAN
KEGG Pathway hsa:55244
Protein Family Multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family
Protein Function
Solute transporter for tetraethylammonium (TEA), 1-methyl-4-phenylpyridinium (MPP), cimetidine, N-methylnicotinamide (NMN), metformin, creatinine, guanidine, procainamide, topotecan, estrone sulfate, acyclovir, ganciclovir and also the zwitterionic cephalosporin, cephalexin and cephradin. Seems to also play a role in the uptake of oxaliplatin (a new 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.

      Mechanism Description
  • Decreased clearance of Methylnaltrexone due to the transporter inhibition by Capmatinib 

Recommended Action
      Management Coadministration of capmatinib with drugs that are substrates of MATE1 and/or MATE2K should generally be avoided. However, if concomitant use is unavoidable, caution is advised, particularly with drugs that have a narrow therapeutic range. Clinical and laboratory monitoring should be considered whenever capmatinib is added to or withdrawn from therapy with these drugs, and the dosages adjusted as necessary. Patients should be monitored for the development of adverse effects.
