AVIAN LYSOZYME PROMOTER

摘要

The present invention provides novel isolated nucleic acids comprising an avian nucleic acid sequence encoding a lysozyme gene expression control region. The isolated nucleic acid of the present invention is useful for reducing the chromosomal positional effect of a transgene operably linked to the lysozyme gene expression control region and transfected into a recipient cell and allows expression of an operably linked heterologous nucleic acid insert in a transfected avian cells such as, for example, an oviduct cell. The isolated avian lysozyme of the present invention may be operably linked with a selected nucleic acid insert encoding a polypeptide desired to be expressed in a transfected cell. The recombinant DNA of the present invention may further comprise a polyadenylation signal sequence or a chicken lysozyme 3' domain.
