CC -!- FUNCTION: Plays a critical role in MHC class II antigen processing by
CC stabilizing peptide-free class II alpha/beta heterodimers in a complex
CC soon after their synthesis and directing transport of the complex from
CC the endoplasmic reticulum to the endosomal/lysosomal system where the
CC antigen processing and binding of antigenic peptides to MHC class II
CC takes place. Serves as cell surface receptor for the cytokine MIF.
CC -!- FUNCTION: [Class-II-associated invariant chain peptide]: Binds to the
CC peptide-binding site of MHC class II alpha/beta heterodimers forming an
CC alpha-beta-CLIP complex, thereby preventing the loading of antigenic
CC peptides to the MHC class II complex until its release by HLA-DM in the
CC endosome. {ECO:0000269|PubMed:1448172}.
CC -!- FUNCTION: [Isoform p41]: Stabilizes the conformation of mature CTSL by
CC binding to its active site and serving as a chaperone to help maintain
CC a pool of mature enzyme in endocytic compartments and extracellular
CC space of antigen-presenting cells (APCs). Has antiviral activity by
CC stymieing the endosomal entry of Ebola virus and coronaviruses,
CC including SARS-CoV-2 (PubMed:32855215). Disrupts cathepsin-mediated
CC Ebola virus glycoprotein processing, which prevents viral fusion and
CC entry. This antiviral activity is specific to p41 isoform
CC (PubMed:32855215). {ECO:0000250|UniProtKB:P04441,
CC ECO:0000269|PubMed:32855215}.
CC -!- SUBUNIT: Homotrimer. In the endoplasmic reticulum (ER) it forms a
CC heterononameric MHC II-Ii complex: 3 MHC class II molecules
CC (heterodimers of an alpha and a beta subunit) bind to the CD74
CC homotrimer (also known as invariant chain or HLA class II
CC histocompatibility antigen gamma chain). In the endosomal/lysosomal
CC system, the CD74 component undergoes sequential degradation by various
CC proteases, including CTSS and CTSL, leaving a small fragment termed
CC CLIP (class-II-associated invariant chain peptide) attached to the MHC
CC class II molecule (alpha-beta-CLIP complex). This processed complex
CC interacts with HLA_DM and HLA_DO heterodimers in order to release CLIP
CC and facilitate the binding of antigenic peptides to the MHC class II
CC molecules. Interacts with CD44; this complex is essential for the MIF-
CC induced signaling cascade that results in B cell survival.
CC {ECO:0000250|UniProtKB:P04441, ECO:0000269|PubMed:12782713,
CC ECO:0000269|PubMed:7477400}.
CC -!- SUBUNIT: [Isoform p41]: Interacts with the mature form of CTSL; the
CC complex survive in neutral pH environment.
