title: A cryptic transcription promoter in the myb oncogene of avian myeloblastosis virus.
abstract: The potential regulatory signals contained in the v-myb oncogene of avian myeloblastosis virus have been inserted upstream to the herpes simplex type 1 thymidine kinase gene in order to test their promoter activity. The isolation of TK+ transformants after transfection of clone 1D(TK-) mouse cells with the resulting recombinant DNAs indicated that the expression of the TK gene was made possible by the myb-derived sequences. Analysis of the TK specific RNA expressed in different TK+ transformants revealed that the regulatory signals contained in v-myb correspond to a weak functional promoter.
