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 Tipiracil due to the transporter inhibition by Brigatinib 

Recommended Action
      Management Caution is advised if brigatinib is used concomitantly with drugs that are substrates of P-gp, BCRP, OCT 1, MATE 1, and/or MATE 2K transport proteins, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever brigatinib is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.
