Background

  • Function

    CD74 (HLA class II histocompatibility antigen gamma chain; HLA-DR antigens-associated invariant chain) is a type II transmembrane protein. CD74 is involved in the formation and transport of MHC class II peptide complexes for the generation of CD4+ T cell responses. Cell surface CD74 serves as a receptor for the cytokine, macrophage migration inhibitory factor (MIF) on many cell types. In immune cells, MIF binding to CD74 induces a signaling cascade that results in regulation of cell proliferation and survival. CD74 has been associated with tumor progression and metastasis. CD74 expression has been suggested to serve as a prognostic factor in many cancers, with higher relative expression behaving as a marker of tumor progression[1].

  • 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
