Names and origin

Protein namesRecommended name:
Multidrug resistance protein
EC=3.6.3.44
Alternative name(s):
P-glycoprotein
Gene names
Name:PGPA
OrganismLeishmania tarentolae (Sauroleishmania tarentolae)
Taxonomic identifier5689 [NCBI]
Taxonomic lineageEukaryota › Euglenozoa › Kinetoplastida › Trypanosomatidae › Leishmania › lizard Leishmania

Protein attributes

Sequence length1548 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

ATP + H2O + xenobiotic(In) = ADP + phosphate + xenobiotic(Out).

Subcellular location

Membrane; Multi-pass membrane protein.

Miscellaneous

In this organism, this protein is encoded by a gene, located in "H circle", a 68 kb duplex DNA circle containing a 30 kb inverted repeat. Acquired resistance to methotrexate in the organism is associated with the amplification of h circles with increasing level of LTPGPA gene transcription.

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.
