Proteolysis of the class II-associated invariant chain generates a peptide binding site in intracellular HLA-DR molecules. Proc. Natl. Acad. Sci. USA. 1991. 88: 3150-3154.

Abstract

HLA-DR molecules are heterodimeric transmembrane glycoproteins that associate intracellularly with a polypeptide known as the invariant (I) chain. Shortly before expression of the HLA-DR αβ dimer on the cell surface, however the I chain is removed from the intracellular αβI complex by a mechanism thought to involve proteolysis . In this report, we show that… (More)
