MARCO (Macrophage receptor with collagenous structure; also scavenger receptor class A member 2/SR­AII) is a 65­70kD pattern recognition receptor/PRR that belongs to class A of the SR family, SRCR superfamily of molecules. It is expressed by macrophages, monocytes and Kupffer cells, and apparently binds to a number of microbes, including Gram+ bacteria (Staph and Strep) and Gram­ bacteria (Neisseria and coliforms), plus crystalline silica. Human MARCO is a 520 amino acid (aa) type II tranamembrane glycoprotein. It contains a 43aa cytoplasmic region and a 456aa extracellular domain/ECD (aa65­520). The ECD possesses one collagen­like region (aa147­419) and an SRCR domain (aa424­519). Human MARCO is believed to form trimers and/or multimers, and these are likely noncovalent associations. Over aa79­520, human and mouse MARCO share 70% aa sequence identity.
