pgp-5 encodes a transmembrane protein that is a member of the P-glycoprotein subclass of the ATP-binding cassette (ABC) transporter superfamily; by homology, PGP-5 is predicted to function as an ATP-dependent efflux pump that protects C. elegans by exporting exogenous toxins; pgp-5 activity is required for defense response to both Gram-negative and Gram-positive bacteria as well as for the response to heavy metal ions, including cadmium, copper, and zinc; pgp-5 is expressed in the intestine as well as in the terminal bulb of the pharynx; basal pgp-5 intestinal expression is regulated by TIR-1, while increased expression in response to stressors is under the contol of the p38 MAPK pathway.
Predicted to enable ATPase-coupled transmembrane transporter activity and efflux transmembrane transporter activity. Involved in several processes, including defense response to bacterium; response to nematicide; and stress response to metal ion. Predicted to be located in plasma membrane. Expressed in intestine. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); carcinoma (multiple); and hematologic cancer (multiple). Is an ortholog of human ABCB1 (ATP binding cassette subfamily B member 1) and ABCB4 (ATP binding cassette subfamily B member 4).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
