Identified are genetic regulatory elements which are part of a natural antisense RNA negative regulatory system in eukaryotic cells. The genetic regulatory elements, designated an antisense initiator sequence, when downstream of and operably linked to a DNA molecule, can transcribe the DNA molecule into RNA transcripts of negative strand polarity that function to bind to, in forming an RNA duplex with, sense RNA transcripts being produced from a target gene to be regulated. The invention relates to recombinant vectors useful for introduction into eukaryotic cells, and methods of using the vectors to regulate expression of a target gene comprising introducing the recombinant vectors into host eukaryotic cells.
