Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells.

Miscellaneous

PGP isoforms differ in their drug transport capabilities: PGP1 and PGP2 can mediate MDR, while PGP3 apparently cannot.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
