Abstract

A cDNA coding for a rat derived CNP (rCNP: C-type natriuretic pepteide), and a rat derived CNP precursor protein and derivatives thereof are disclosed. The rat derived CNP precursor is represented by the following amino acid sequence. PA1 Met His Leu Ser Gln Leu Ile Ala Cys Ala Leu Leu Leu Ala Leu Leu Ser Leu Arg Pro Ser Glu Ala Lys Pro Gly Thr Pro Pro Lys Val Pro Arg Thr Pro Pro Gly Glu Glu Leu Ala Glu Pro Gln Ala Ala Gly Gly Asn Gln Lys Lys Gly Asp Lys Thr Pro Gly Gly Gly Gly Ala Asn Leu Lys Gly Asp Arg Ser Arg Leu Leu Arg Asp Leu Arg Val Asp Thr Lys Ser Arg Ala Ala Trp Ala Arg Leu Leu His Glu His Pro Asn Ala Arg Lys Tyr Lys Gly Gly Asn Lys Lys Gly Leu Ser Lys Gly Cys Phe Gly Leu Lys Leu Asp Arg Ile Gly Ser Met Ser Gly Leu Gly Cys The rCNP precursor and its derivatives are novel and have natriuretic and hypotensive activities.
