Nucleotide sequence of cloned cDNA encoding bovine arginine vasopressin-neurophysin II precursor

Abstract

The sequence of a cDNA encoding the nonapeptide arginine vasopressin (AVP) and its carrier protein, neurophysin II (NpII) from bovine hypothalamus, proves that the 166-amino acid precursor molecule contains a signal peptide of 19 amino acids followed directly by AVP connected to NpII by a Gly-Lys-Arg sequence. The carboxy-terminal region of the precursor contains a naturally occurring glycopolypeptide of 39 amino acids which is separated from NpII by a single arginine residue.
