ABCC4
ATP-binding cassette sub-family C member 4, also known as the multidrug resistance-associated protein 4 or multi-specific organic anion transporter B, is a protein that in humans is encoded by the ABCC4 gene.
ABCC4 acts as a regulator of intracellular cyclic nucleotide levels and as a mediator of cAMP-dependent signal transduction to the nucleus. MRP4/ABCC4 also transports prostaglandins, for example PGE2, out of the cell where they can bind receptors.
MRP4/ABCC4 expression is dysregulated in several cancers and is also upregulated in peritoneal endometriosis.
