Molecular cloning and nucleotide sequence of complementary DNA encoding rabbit alpha 1-acid glycoprotein.

Alpha 1-acid glycoprotein (AGP) complementary DNA clone has been isolated from an acute phase rabbit liver library. Complete and full-length nucleotide sequence of this cDNA has been determined. The cDNA contains 35 nucleotides 5' untranslated region followed by 606 nucleotides of coding region and a 112 nucleotides 3' untranslated region. Comparison of this sequence with that of human, rat and mouse reveals a high degree of homology with human alpha 1-AGP. Northern blot analysis of messenger RNA for alpha 1-AGP in normal and acute livers demonstrates remarkable induction of transcription of this gene in rabbit in response to acute inflammation by the administration of turpentine. Such a response of AGP gene expression makes it a major member of the acute phase responsive genes in rabbit liver.
