| Research Abstract |
1). Three types of isozyme of peptidylarginine deiminase were found and its characterization and tissue distribution were described.
2). Molecular cloning and sequencing of cDNA coding for mouse uterus peptidylarginine deiminase were performed. The amini terminus of the enzyme was predicted to be Nーacety1-methionine which corresponds to the initiatione. The MW of the mature enzyme is calculated to be 76,260 from deduced amino acid sequence.
3). The cloning of the genomic DNA was carried out, and the results demonstrated that the mouse peptidylarginine deiminase gene was a single copy gene. Then tow clones which covered 65% of the cDNA were isolated from mouse genomic libraries.
4). Gene expression plasmid of peptidylarginine deiminase cDNA was constracted. The EcoR1 digestsof cDNA fragments, PAD1 and PAD24 were ligated its 5'-EcoR1-3'-HindIII fragment was inserted to E. coil expression vector pKK223-3.
