Proteasome 20 S antibody was raised in rabbit using a Mixture of synthetic peptides corresponding to residues C R(207) V I L G N/D E L P K F Y D E(220) of human and mouse proteasome 20 LMP2 as the immunogen.
LMP2 is a catalytic subunit of the 20S proteasome and, upon interferon gamma-induction, replaces the delta subunit. LMP2 alters the specificity of the 20S proteasome and is critical for the production of MHC class I ligands, production of T-lymphocytes, and is suggested to increase the efficiency of antigen presentation of the immune response.
