Upon dissociation from CNX, the heavy chain of (MHC) class I binds ??2 microglobulin (b2m) and is incorporated into the peptide-loading complex.

All CD1 proteins studied to date are expressed on the surface of cells as type I transmembrane proteins that associate noncovalently with ??2-microglobulin

The gene expression of TAP1, TAP2, tapasin, ??2m and HLA-?? HC is up-regulated in mature DC.
