title: Evidence for the repetitive domain structure of pig calpastatin as demonstrated by cloning of complementary DNA.
abstract: A clone of complementary DNA (cDNA) coding for pig heart calpastatin was isolated using synthetic oligonucleotide probes. The amino acid sequence deduced from the nucleotide sequence revealed the occurrence of a repetitive sequence at the interval of 140 amino acids, substantiating the multidomain structure of calpastatin. A portion of the sequence of 251 amino acid residues predicted for pig heart calpastatin (107 kDa) was found to be identical with that of a peptide fragment derived from pig erythrocyte calpastatin (68 kDa) and sequenced by Edman degradation.
