Background: CD74

CD74, also known as the MHC class II associated invariant chain (Ii), is a type II transmembrane protein which binds to the peptide binding groove of newly synthesized MHC class II alpha/beta heterodimers and prevents their premature association with endogenous polypeptides. CD74 is produced in molar excess over MHC class II and some of this is expressed by an unknown pathway on the cell surface independent of or in association with MHC class II molecules. The half life of CD74 on the cell surface is only 3 to 4 min after which it is internalized. It has been proposed that cell surface CD74 binds MHC class II molecules which have lost their antigenic peptide leading to internalization and reloading with antigenic peptide. The transport route of class II alpha/beta/Ii complexes is regulated selectively by two forms of CD74 (p33 and p35) which are generated by the use of alternative translation initiation sites. CD74 is expressed primarily by antigen presenting cells such as B lymphocytes (from before the pre-B cell stage to before the plasma cell stage), macrophages and monocytes together, with many epithelial cells. CD74 may exist in different isoforms ranging in size from 33 to 41kDa, depending on genetic splicing.
