Indicative of a protease inhibitor, usually a serine protease inhibitor. Structure is a disulfide rich alpha+beta fold. BPTI (bovine pancreatic trypsin inhibitor) is an extensively studied model structure. Certain family members are similar to the tick anticoagulant peptide (TAP). This is a highly selective inhibitor of factor Xa in the blood coagulation pathways. TAP molecules are highly dipolar, and are arranged to form a twisted two- stranded antiparallel beta-sheet followed by an alpha helix. Length = 53
Serine protease inhibitors. One member of the family is encoded by an alternatively-spliced form of Alzheimer's amyloid beta-protein.
>PF00014 Kunitz_BPTI: Kunitz/Bovine pancreatic trypsin inhibitor domain; InterPro: IPR002223 The majority of the sequences having this domain belong to the MEROPS inhibitor family I2, clan IB; the Kunitz/bovine pancreatic trypsin inhibitor family, they inhibit proteases of the S1 family [] and are restricted to the metazoa with a single exception: Amsacta moorei entomopoxvirus
They are short (~50 residue) alpha/beta proteins with few secondary structures. The fold is constrained by 3 disulphide bonds. The type example for this family is aprotinin (bovine pancreatic trypsin inhibitor) [] (or basic protease inhibitor), but the family includes numerous other members [, , , ], such as snake venom basic protease; mammalian inter-alpha-trypsin inhibitors; trypstatin, a rodent mast cell inhibitor of trypsin; a domain found in an alternatively-spliced form of Alzheimer's amyloid beta-protein; domains at the C-termini of the alpha(1) and alpha(3) chains of type VII and type VI collagens; and tissue factor pathway inhibitor precursor.; GO: 0004867 serine-type endopeptidase inhibitor activity; PDB: 1YC0_I 4DTG_K 1TFX_D 1ADZ_A 1BF0_A 3OFW_A 1SHP_A 3M7Q_B 3GYM_J 1BHC_G ....
