Abstract
DNA primers each having a nucleotide sequence substantially complementary to a nucleotide sequence which codes for Gly-Lys-Arg, Gly-Lys-Lys or Gly-Arg-Arg; methods for amplifying a polynucleotide which codes for a peptide or a precursor protein thereof using said DNA primer; screening methods for a polynucleotide which codes for a peptide comprising an amino acid sequence of Gly-Lys-Arg, Gly-Lys-Lys or Gly-Arg-Arg or a precursor protein thereof from a DNA library, etc. using said DNA; the polynucleotide obtained by said screening method; and the peptide or its precursor protein encoded by said polynucleotide, or a salt thereof. When the DNA primer of the present invention is used, the DNA which codes for a peptide having a useful physiological activity or a precursor protein thereof can be efficiently cloned.
