#Section 2: General Biology
  1. Class-I MHC gene encodes glycoprotein molecule which expressed on the surface of all nucleated cells and platelets. 

  2. MHC-I molecule contains a 45KDa α-chain associated non-covalentely with a 12KDa β2 microglobulin molecule. 

  3. Association of α-chain and β2 microglobulin is required for expression of class-I MHC molecule on cell membrane.

  4. Major function of MHC-I is to bind peptide antigen and present to CD4 T cells.
