Rabbit muscle creatine phosphokinase. CDNA cloning, primary structure and detection of human homologues.
A cDNA library was constructed from rabbit muscle poly(A) RNA. Limited amino acid sequence information was obtained on rabbit muscle creatine phosphokinase and this was the basis for design and synthesis of two oligonucleotide probes complementary to a creatine kinase cDNA sequence which encodes a pentapeptide. Colony hybridizations with the probes and subsequent steps led to isolation of two clones, whose cDNA segments partially overlap and which together encode the entire protein. The primary structure was established from the sequence of two cDNA clones and from independently determined sequences of scattered portions of the polypeptide. The reactive cysteine has been located to position 282 within the 380 amino acid polypeptide. The rabbit cDNA hybridizes to digests of human chromosomal DNA. This reveals a restriction fragment length polymorphism associated with the human homologue(s) which hybridizes to the rabbit cDNA.
