Cloning and nucleotide sequence of a human Zn-alpha 2-glycoprotein cDNA and chromosomal assignment of its gene

Biochem Biophys Res Commun. 1991 Jun 14;177(2):696-703. doi: 10.1016/0006-291x(91)91844-3.


A cDNA clone of Zn-alpha 2-glycoprotein (Zn alpha 2gp) was isolated from a human prostate library. The amino acid sequence of prostate Zn alpha 2gp deduced from the nucleotide sequence was identical to the one previously reported on the Zn alpha 2gp protein purified from human blood plasma, except at three positions: the 65th and 222nd amino acid residues were Gln (----Glu) and Glu (----Gln), and there was a two amino acid insertion (Ile-Phe) between the 75th (Glu) and 76th (Met) amino acids. Southern blot analysis of human genomic DNA, however, suggested a single gene encoding Zn alpha 2gp. Using a panel of rodent-human somatic cell hybrids, the Zn alpha 2 gp gene was assigned to human chromosome 7.
