Webb16 apr. 2002 · 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). WebbAlso, the invariant chain transports the MHC class II molecule from the Golgi apparatus to the endocytic compartments. Signals in the cytoplasmic tail of Ii lead to proper sorting of MHC class II. In the endocytic compartments Ii is cleaved to leave a peptide fragment (CLIP) in the binding groove.
