The ABCC12 (ATP-binding cassette subfamily C member 12) protein, also known as multidrug resistance-associated protein 9 (MRP9), is a member of the ABC transporter superfamily. These proteins are primarily involved in ATP-dependent transport of various substrates across cellular membranes. ABCC12 is encoded by the ABCC12 gene located on human chromosome 16q12.1 and shares structural homology with other MRP family members, featuring characteristic transmembrane domains and nucleotide-binding domains. Although its exact physiological role remains less defined compared to well-studied transporters like ABCC1 or ABCC4. emerging evidence suggests ABCC12 may participate in the efflux of cyclic nucleotides (e.g., cAMP, cGMP) or xenobiotics, potentially influencing drug disposition and cellular detoxification.
Recombinant ABCC12 protein, produced through heterologous expression systems (e.g., mammalian or insect cells), enables functional characterization of its transport mechanisms. Studies using purified recombinant ABCC12 have helped identify potential substrates and inhibitors, shedding light on its interaction with antiviral agents, chemotherapeutics, and endogenous molecules. Aberrant ABCC12 expression has been tentatively linked to clinical conditions, including hearing loss (via its role in maintaining cochlear homeostasis) and familial primary angle-closure glaucoma, though these associations require further validation. In cancer research, recombinant ABCC12 serves as a tool to investigate multidrug resistance phenotypes, particularly in malignancies where its overexpression correlates with reduced chemosensitivity. Structural studies of the recombinant protein also aim to resolve its 3D architecture, facilitating targeted drug design. Despite progress, ABCC12's biological significance and therapeutic potential remain under active exploration.
