Supplementary information

The MRP4 protein also known as Multidrug Resistance Protein 4 or ABCC4 is an ATP-binding cassette transporter with a mass of approximately 150 kDa. This protein is expressed in various tissues including the liver kidney and brain. It plays a mechanical role by transporting organic anions drugs and other xenobiotic compounds across cellular membranes. MRP4 is part of the wider ATP-binding cassette (ABC) transporter family which actively pumps substrates against concentration gradients using ATP hydrolysis.
Biological function summary

MRP4 impacts processes like pharmacokinetics and drug metabolism. The protein contributes to the efflux of endogenous substrates and medication from cells affecting their absorption and excretion. MRP4 also functions as part of a larger transporter complex working with other similar proteins to manage cellular detoxification systems. The MRP4 transporter maintains cellular homeostasis by removing harmful substances supporting cellular defense mechanisms against xenobiotic and endogenous compounds.

Pathways

MRP4 integrates into cellular processes such as prostaglandin and cyclic nucleotide signaling pathways. These pathways are important in regulating inflammatory responses and cardiovascular functions. MRP4 interacts with other proteins including MRP1 and MRP5 which facilitate the movement of similar substrates providing flexibility and redundancy within cellular transport systems. This involvement enables MRP4 to modulate biological effects via alteration in prostaglandin levels.

MRP4 connects to conditions such as cancer and viral infections. Elevated expression of MRP4 can lead to drug resistance in cancer therapy complicating treatment strategies. In viral infections MRP4 modulates the availability of nucleoside analogs used in antiviral therapies. The protein's role aligns with other transporters like P-glycoprotein showcasing its involvement in the multidrug resistance phenotype. Consequently understanding MRP4's function can aid in the development of new therapeutic approaches targeting these disorders.

Target data

ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes physiological compounds and xenobiotics from cells (PubMed : 11856762, PubMed : 12523936, PubMed : 15364914, PubMed : 38886124, PubMed : 40138312). Transports a range of endogenous molecules that have a key role in cellular communication and signaling, including cyclic nucleotides such as cyclic AMP (cAMP) and cyclic GMP (cGMP), bile acids, steroid conjugates, urate, and prostaglandins (PubMed : 11856762, PubMed : 12523936, PubMed : 12835412, PubMed : 12883481, PubMed : 15364914, PubMed : 15454390, PubMed : 16282361, PubMed : 17959747, PubMed : 18300232, PubMed : 26721430, PubMed : 38886124, PubMed : 40138312). Mediates the ATP-dependent efflux of glutathione conjugates such as leukotriene C4 (LTC4) and leukotriene B4 (LTB4) too. The presence of GSH is necessary for the ATP-dependent transport of LTB4, whereas GSH is not required for the transport of LTC4 (PubMed : 17959747). Mediates the cotransport of bile acids with reduced glutathione (GSH) (PubMed : 12523936, PubMed : 12883481, PubMed : 16282361). Transports a wide range of drugs and their metabolites, including anticancer, antiviral and antibiotic molecules (PubMed : 11856762, PubMed : 12105214, PubMed : 15454390, PubMed : 17344354, PubMed : 18300232). Confers resistance to anticancer agents such as methotrexate (PubMed : 11106685).
