Human ABCC4(Multidrug resistance-associated protein 4) ELISA Kit

Background

ABCC4, also known as multidrug resistance-associated protein 4 (MRP4), is an ATP-binding cassette transporter expressed in various tissues, including the liver, kidneys, and endothelial cells of the blood-brain barrier. It exports a wide range of substrates, including cyclic nucleotides, prostaglandins, antiviral drugs, and chemotherapeutic agents, from cells. ABCC4’s activity plays a critical role in cellular signaling by regulating intracellular levels of cyclic AMP and GMP. It is also involved in drug resistance, where its overexpression limits the intracellular accumulation of therapeutic agents. ABCC4 is upregulated in response to oxidative stress and inflammation, highlighting its role in protecting cells from toxic insults. Its diverse substrate specificity and involvement in drug efflux make ABCC4 a significant target in pharmacological research and disease management.
