Background

Function：Plays a critical role in MHC class II antigen processing by stabilizing peptide-free class II alpha/beta heterodimers in a complex soon after their synthesis and directing transport of the complex from the endoplasmic reticulum to the endosomal/lysosomal system where the antigen processing and binding of antigenic peptides to MHC class II takes place. Serves as cell surface receptor for the cytokine MIF; Binds to the peptide-binding site of MHC class II alpha/beta heterodimers forming an alpha-beta-CLIP complex, thereby preventing the loading of antigenic peptides to the MHC class II complex until its release by HLA-DM in the endosome; Stabilizes the conformation of mature CTSL by binding to its active site and serving as a chaperone to help maintain a pool of mature enzyme in endocytic compartments and extracellular space of antigen-presenting cells (APCs). Has antiviral activity by stymieing the endosomal entry of Ebola virus and coronaviruses, including SARS-CoV-2 (PubMed:32855215). Disrupts cathepsin-mediated Ebola virus glycoprotein processing, which prevents viral fusion and entry. This antiviral activity is specific to p41 isoform (PubMed:32855215)

Subcellular Localization：Cell membrane; Single-pass type II membrane protein; Endoplasmic reticulum membrane; Golgi apparatus, trans-Golgi network; Endosome; Lysosome; Secreted; Late endosome; Lysosome

Expression：
Tissue_specificity:Protein levels are detectable in urine; it accounts for 10% of total CD74 expression in B cells and 70% of total CD74 expression in other B cells.

Isoforms & Post-Translational Modification：P04233 has 5 isomers: P04233-1: 33516 Da (predicted); P04233-2: 26399 Da (predicted); P04233-3: 18328 Da (predicted); P04233-4: 31492 Da (predicted); P04233-5: 24375 Da (predicted).
O-glycosylated with core 1 or possibly core 8 glycans (PubMed:22171320, PubMed:23234360). Contains chondroitin sulfate (PubMed:25326458)

Subunit：Homotrimer. In the endoplasmic reticulum (ER) it forms a heterononameric MHC II-Ii complex: 3 MHC class II molecules (heterodimers of an alpha and a beta subunit) bind to the CD74 homotrimer (also known as invariant chain or HLA class II histocompatibility antigen gamma chain). In the endosomal/lysosomal system, the CD74 component undergoes sequential degradation by various proteases, including CTSS and CTSL, leaving a small fragment termed CLIP (class-II-associated invariant chain peptide) attached to the MHC class II molecule (alpha-beta-CLIP complex). This processed complex interacts with HLA_DM and HLA_DO heterodimers in order to release CLIP and facilitate the binding of antigenic peptides to the MHC class II molecules. Interacts with CD44; this complex is essential for the MIF-induced signaling cascade that results in B cell survival
