FIELD: biotechnology.
SUBSTANCE: promoter, characterised by sequence of the nucleic acid SEQ ID NO: 04, is promoter SV40 shortened from the 5'-terminus. The promoter is used for expression of heterologous polypeptides, as well as for selection of cells expressing heterologous polypeptides.
EFFECT: invention enables to identify producer cells with restricted expression of heterologous polypeptide due to the use of a promoter with reduced power.
