ABCC4 (ATP-binding cassette, subfamily c, member 4) also known as MRP4 (Multidrug resistance associated protein 4) or MOATB, is a protein that in humans is encoded by the ABCC4 gene. It belongs to a large family of transmembrane proteins involved in active transport of substrates out of cells. This gene is mapped to chromosome 13q32. ABCC4/MRP4 acts as an independent regulator of intracellular cyclic nucleotide levels and as a mediator of cAMP-dependent signal transduction to the nucleus. The antiproliferative effect of MPR4 inhibition was related to cAMP-dependent PKA activation and CREB phosphorylation. Pharmacologic inhibition of its activity or knockdown of the protein via RNA interference resulted in reduced migration of DCs from human skin explants and of in vitro-generated Langerhans cells. It has been found that MRP4 contributes to migration of DCs toward draining lymph nodes and therefore has a role in the initiation of an immune response.
