Gene: [11q1/MDU1] antigen MDU1, heavy subunit (p40, monoclonal antibodies 4F2, 44D7); sodium-calcium exchanger (NACAE); [M4F2 MGP4F2 ]

COM

MDU: onoclonal, uke niversity.

MOP

The antigen determinant that is recognized by 4F2 antibodies is located on the surface of the 65-kD subunit of the membrane glycoprotein having MM over 100 kD. The second subunit of this glycoprotein is not glycosylated; it has the MM about 40 kD (Hemler-1982). Nothing is known about its genetics."

GEN

The gene length is about 8 kb. Exons: 9 (Gottesdiener-1988). The peptide product consists of 155 amino acid residues (Lumadue-1987)."
