General annotation (Comments)
| Function | Solute transporter for tetraethylammonium (TEA), 1-methyl-4-phenylpyridinium (MPP), cimetidine, N-methylnicotinamide, metformin, creatinine, guanidine, procainamide, topotecan, estrone sulfate, acyclovir, and ganciclovir. Responsible for the secretion of cationic drugs across the brush border membranes. Ref.1 Ref.6 Ref.7 |
| Subcellular location | Cell membrane; Multi-pass membrane protein Potential. Note: Localized at the brush border membranes of the proximal tubules. |
| Tissue specificity | Isoform 3 is predominantly expressed in kidney. Isoform 6 is expressed in brain. Ref.1 |
| Sequence similarities | Belongs to the multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family. [View classification] |
| Biophysicochemical properties | Kinetic parameters: KM=0.76 mM for TEA Ref.1 Ref.7 KM=0.11 mM for MPP KM=0.12 mM for cimetidine KM=1.98 mM for metformin KM=4.2 mM for guanidine KM=1.58 mM for procainamide KM=0.06 mM for topotecan KM=0.85 mM for estrone sulfate KM=4.32 mM for acyclovir KM=4.28 mM for ganciclovir Vmax=0.88 nmol/min/mg enzyme toward TEA Vmax=0.575 nmol/min/mg enzyme toward MPP Vmax=0.115 nmol/min/mg enzyme toward cimetidine Vmax=0.845 nmol/min/mg enzyme toward metformin Vmax=0.58 nmol/min/mg enzyme toward guanidine Vmax=3.385 nmol/min/mg enzyme toward procainamide Vmax=0.13 nmol/min/mg enzyme toward topotecan Vmax=0.425 nmol/min/mg enzyme toward estrone sulfate Vmax=0.945 nmol/min/mg enzyme toward acyclovir Vmax=0.805 nmol/min/mg enzyme toward ganciclovir pH dependence: Optimum pH is 9.0.
