The antibody MEM-240 recognizes an extracellular epitope between amino acids 698-1262 of CD222 (IGF2 receptor), a ubiquitously expressed 250 kDa multifunctional type I transmembrane protein. The majority of CD222 is found in the late endosomal/prelysosomal compartment, 5-10 % in the plasma membrane and the truncated (220 kDa) form of CD222 is present in human and bovine serum.
Insulin like growth factor 2 receptorprovided,CD222 (CIMPR, cation-independent mannose 6-phosphate receptor, IGF2 receptor) is a ubiquitously expressed 250 kDa transmembrane protein. No more than 10 % of CD222 is present on the cell surface where it serves as a multifunctional receptor. Intracellular (major) fraction of CD222 is involved in transport of newly synthesized lysosomal enzymes modified by mannose 6-phosphate from Golgi apparatus to lysosomes. The cell surface CD222 binds and internalizes exogeneous mannose 6-phosphate-containing ligands. Importantly, CD222 is crutial for internalization and degradation of insulin-like growth factor 2, thus controling cell growth. CD222 also complexes CD87 (urokinase-type plasminogen-activator receptor), plasminogen and latent TGF-beta, last but not least CD222 serves as a receptor for heparanase and even for Listeria.,IGF2R, MPR1, CIMPR, MPR300, M6P-R
