  • Descrição: The organization and sequence of the rat preprolactin gene has been investigated. Analysis of two different plasmids containing pituitary cDNA inserts has provided the complete 681-nucleotide coding sequence of preprolactin as well as 17 nucleotides preceding the initiation codon and 90 nucleotides following the termination codon. Digestion of rat chromosomal DNA with the restriction endonuclease Eco RI followed by size fractionation and hybridization to a labeled prolactin cDNA probe has demonstrated that prolactin genomic sequences are located on 6.0-, 3.9-, and 2.9-kilobase fragments. The 6.0- and 3.9-kilobase fragments were isolated from a library of cloned rat DNA fragments. The sequence of more than 1800 nucleotides of the cloned DNA has been determined. The sequenced region contains coding regions of 180 and 189 nucleotides which specify the COOH-terminal 123 amino acids of the 227-amino-acid sequence of rat preprolactin. These coding regions are separated by an intervening sequence of 597 nucleotides. At least one other large intervening sequence separates this region from the region coding for the NH2-terminal portion of preprolactin. Hybridization experiments suggested that the intervening sequences of the rat prolactin gene contain DNA sequences which are repeated elsewhere in the rat genome.
