Function

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).

Activity summary

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.

Associated diseases and disorders

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.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-MRP1 antibody [MRPr1] (ab3368)

    IHC staining of ab3368 on formalin-fixed paraffin-embedded human liver tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., the tissue was incubated with a 1/20 dilution of the primary antibody for 60 minutes at room temperature. After incubation with biotinylated anti-rat antibody, the tissue was labeled with BioLegend's HRP labeling reagent followed by addition of DAB chromogen for detection and hematoxylin counterstaining, according to the protocol provided. The image was captured with a 40X objective. Scale bar 50 μm

    Immunocytochemistry/ Immunofluorescence - Anti-MRP1 antibody [MRPr1] (ab3368)

    ICC/IF image of ab3368 stained HepG2 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3368,5μg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rat IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-MRP1 antibody [MRPr1] (ab3368)

    IHC image of ab3368 staining in human lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab3368, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
