CD74, also known as CLIP, is a 33.5kD homotrimer and functions as a MHC class II chaperone for exogenous peptides and other MHC class II molecules. CD74 binds MIF and regulates innate and adaptive immunity through CD44 signaling. It is found primarily on B-cells, monocytes, macrophages and dendritic cells, but can also be found on activated T-cells, endothelial and epithelial cells.
