| Addtional Information | FUNCTION:Inhibition of trypsin.MISCELLANEOUS:The sequence of variant A is shown.MISCELLANEOUS:Electrophoresis identifies three genetically distinct variants, A, B, and C, that are inherited as codominant alleles.SIMILARITY:Belongs to the protease inhibitor I3 (leguminous Kunitz-type inhibitor) family.CAUTION:Ref.4 sequence was originally thought to be rat caltrin.A number of peptide fragments were derived from a trypsin digest of caltrin and soybean trypsin inhibitor was used to stop the digestion. It appears that some of the inhibitor was also digested and sequenced. |
