Anti-ccmD antibodies are used in antigen-specific immunodetection in biological samples. The target ccmD is a known alias name of the protein major facilitator superfamily domain containing 8, encoded by the MFSD8 gene in humans. This 518-amino acid residue protein is believed to be a carrier that transport small solutes by using chemiosmotic ion gradients. It is localized to the lysosomes of the cell and features glycosylated post-translational modifications. In terms of tissue expression, it is noted to be expressed at very low levels in all tissues tested.
