Title: Amino acid sequence elucidation of human acrosin-trypsin inhibitor (HUSI-II) reveals that Kazal-type proteinase inhibitors are structurally related to beta-subunits of glycoprotein hormones. Author: Fink E, Hehlein-Fink C, Eulitz M. Journal: FEBS Lett; 1990 Sep 17; 270(1-2):222-4. PubMed ID: 2226783. Abstract: The amino acid sequence of the acrosin-trypsin inhibitor HUSI-II from human seminal plasma is presented which unequivocally identifies HUSI-II as being of Kazal-type. In addition, the HUSI-II sequence shows a striking similarity to the middle part of glycoprotein hormone beta-subunits thus revealing a hitherto unknown structural and evolutionary relationship between Kazal-type inhibitors and glycoprotein hormones.[Abstract] [Full Text] [Related] [New Search]
