[[http://www.uniprot.org/uniprot/CATL1_HUMAN CATL1_HUMAN]] Important for the overall degradation of proteins in lysosomes. [[http://www.uniprot.org/uniprot/HG2A_HUMAN HG2A_HUMAN]] 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.
