Title: Delivery of functional protein sequences by translocating polypeptides
Inventor: BENNETT ROBERT P
IPC: C12N5/10
Filed: 2000-03-31
Abstract: The invention provides methods for modulating a cellular process by contacti ng a cell in culture with a cell process-modifying molecule attached to a translocating polypeptide. For example, in one embodiment, a cell in culture  is transfected with a target gene by contacting the cell in culture with a polynucleotide (that contains the target gene) attached to a translocating polypeptide. In another embodiment, expression of a target gene product in a  cell in culture that contains a target gene under control of one or more regulatory elements is modulated by contacting the cell in culture with one or more regulatory agents attached to a translocating polypeptide. The one or more regulatory agents are translocated into the cell in culture and interac t therein with the one or more regulatory elements to modulate expression of t he target gene product by the cell.
