Protein attributes
| Sequence length | 1281 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Mediates ATP-dependent export of organic anions and drugs from the cytoplasm. Hydrolyzes ATP with low efficiency By similarity. |
| Catalytic activity | ATP + H2O + xenobiotic(In) = ADP + phosphate + xenobiotic(Out). |
| Subcellular location | Cell membrane; Multi-pass membrane protein By similarity. |
| Miscellaneous | PGP isoforms differ in their drug transport capabilities: PGP1 and PGP2 can mediate MDR, while PGP3 apparently cannot. |
| Sequence similarities | Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily. [View classification] Contains 2 ABC transmembrane type-1 domains. Contains 2 ABC transporter domains. |
