Abstract

Cloned cDNAs encoding the precursor protein for gonadotropin-releasing hormone (Gn-RH) and prolactin release-inhibiting factor (PIF) were isolated from libraries derived from human and rat hypothalamic mRNA. Nucleotide sequence analyses predict precursor proteins of 92 amino acids for both species and show identity between the human placental and human hypothalamic precursor proteins. Whereas the Gn-RH peptide structure is completely conserved in human and rat, the PIF domain of the precursor displays 70% interspecies homology. Genomic analyses revealed the presence of a single Gn-RH-PIF gene in human and rat containing sequences corresponding to the cDNA distributed across four exons.
