Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E.coli-derived human MRP4 recombinant protein (Position: M1-P370). (reported region: M1-P370).
- Molecular weight context: reported MW: 47 kDa; calculated MW: 149527 MW
- Reactivity: Rat,Mouse,Human
- Applications: IHC, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
Multidrug resistance-associated protein 4; Multidrug resistance-associated protein 4. ABCC4 (Atp-binding cassette, subfamily c, member 4) also known as MRP4 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 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 ABCC4 inhibition was related to cAMP-dependent PKA activation and CREB phosphorylation. Pharmacologic inhibition of ABCC4 activity or knockdown of ABCC4 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 ABCC4 contributes to migration of DCs toward draining lymph nodes and therefore has a role in the initiation of an immune response. Functional note: May be an organic anion pump relevant to cellular detoxification. Reported localization: Membrane; Multi-pass membrane protein. Expression/tissue context: Widely expressed, with particularly high levels in prostate, but is barely detectable in liver.
