Cloning and expression analysis of the cDNA encoding rat Zn-alpha 2-glycoprotein

Gene. 1994 Aug 5;145(2):245-9. doi: 10.1016/0378-1119(94)90014-0.


We report here the nucleotide (nt) sequence of a rat liver cDNA encoding Zn-alpha 2-glycoprotein (Zn-alpha 2-gp), a plasma protein with a high degree of sequence similarity to class-I major histocompatibility complex (MHC) antigens. The deduced amino acid (aa) sequence contains the coding information for 293 aa residues and shows 60% identity with the aa sequence of human Zn-alpha 2-gp and 35% identity with that corresponding to the extracellular domains of RT1, a rat class-I MHC antigen. Northern blot analysis showed that rat Zn-alpha 2-gp is expressed in liver, but not in a wide number of tissues, including prostate, mammary gland, kidney, intestine, lung, pancreas, ovary, uterus, thyroid, placenta, spleen, brain and heart.
