Iwao Ohkubo, Kotoku Kurachi,* Toshihide Takasawa, Hiroyuki Shiokawa, and Makoto Sasaki abstract: A Xgtll cDNA library containing DNA inserts prepared from human liver mRNA has been screened with an antibody to human «2-thiol proteinase inhibitor that was isolated from fresh plasma. Eighteen positive clones were isolated from one million phage, and each was plaque purified. The cDNA insert of one of these phage was sequenced and shown to code for «2-thiolproteinase inhibitor as identified by a partial amino acid sequence of the light chain of a2-thiol proteinase inhibitor. This cDNA insertcontained 1529 base pairs coding for thecomplete a2-thiol proteinase inhibitor. It included 45 base pairs of 5'noncoding sequence, 1281 base pairs that code for pre «2-thiol proteinase inhibitor, a stop codon, 160 base pairs of 3'noncoding sequence, and 40 base pairs of poly (A) tail. The noncoding sequence on the 3'end contained a potential recognition site (AATAAA) for processing and polyadenylation of precursor messenger RNA.The amino acidsequence of a2-thiol proteinase inhibitor de-duced from the cDNA showed a striking similarity (overall homology at 74%) to that of bovine low molecular weight (LMW) kininogen, including two internally repeated sequences and a nonapeptide sequence of bradykinin. These data clearly indicated that a2-thiol proteinase inhibitor and LMW kini-nogen are identical. This was further supported by immu-nological cross-reactivity between «2-thiol proteinase inhibitor and LMW kininogen. When the amino acidsequence of «2-thiol proteinase inhibitor was compared with those for several lowmolecular weight thiol proteinase inhibitors, in-
