Supplementary information

MRP1 also known as ABCC1 is a transporter protein with a mass of approximately 190 kDa. This protein belongs to the ATP-binding cassette (ABC) transporter family. MRP1 actively exports a variety of substrates from cells by hydrolyzing ATP to ADP and inorganic phosphate. You can find MRP1 expressed in many tissues including the lung testis and kidney. It helps in cellular detoxification by exporting organic anions and other conjugated metabolites.
Biological function summary

This protein functions as an important determinant of multidrug resistance in cancer treatment. MRP1 can form part of a larger protein complex that includes other transporters like MRP2. Through its activity MRP1 protects tissues from toxic substances by transporting them out of the cell. Its role in transporting glutathione-conjugated compounds highlights its importance in cellular defense mechanisms against oxidative stress and xenobiotics.

Pathways

MRP1 participates in the glutathione metabolism and the xenobiotic efflux pathways. Both pathways involve cellular detoxification and the accumulation of anomalies can cause harmful effects in the body. MRP1 works with proteins such as GSTP1 which conjugates toxic substances with glutathione preparing them for export by MRP1. This coordination ensures efficient detoxification and protection of cells from damage.

MRP1 has associations with several conditions particularly drug resistance in various cancers and chronic obstructive pulmonary disease (COPD). In cancer MRP1 overexpression often results in reduced treatment efficacy due to chemotherapy drugs being expelled from the cell helping to resist their cytotoxic effects. Research indicates a connection between MRP1 and P-glycoprotein (ABCB1) in cancer drug resistance pointing to a broader resistive mechanism in which multiple transporters are involved.

Target data

Mediates export of organic anions and drugs from the cytoplasm (PubMed : 10064732, PubMed : 11114332, PubMed : 16230346, PubMed : 7961706, PubMed : 9281595). Mediates ATP-dependent transport of glutathione and glutathione conjugates, leukotriene C4, estradiol-17-beta-o-glucuronide, methotrexate, antiviral drugs and other xenobiotics (PubMed : 10064732, PubMed : 11114332, PubMed : 16230346, PubMed : 7961706, PubMed : 9281595). Confers resistance to anticancer drugs by decreasing accumulation of drug in cells, and by mediating ATP- and GSH-dependent drug export (PubMed : 9281595). Hydrolyzes ATP with low efficiency (PubMed : 16230346). Catalyzes the export of sphingosine 1-phosphate from mast cells independently of their degranulation (PubMed : 17050692). Participates in inflammatory response by allowing export of leukotriene C4 from leukotriene C4-synthezing cells (By similarity). Mediates ATP-dependent, GSH-independent cyclic GMP-AMP (cGAMP) export (PubMed : 36070769). Thus, by limiting intracellular cGAMP concentrations negatively regulates the cGAS-STING pathway (PubMed : 36070769).
