Abstract
The present invention provides methods and compositions for protein delivery. The invention features virus like particles, methods of making virus like particles and methods of using virus like particles to deliver proteins to a cell, to provide protein therapy and to treat diseases or disorders. The invention also features methods of targeting a protein to a cell, methods of protein therapy and methods of treating diseases or disorders using a TUS protein, a NLS or NES identified from full length TUS.
Claims18
A pharmaceutical composition comprising a VLP which further comprises a Gag fusion protein comprising a matrix protein, a capsid protein, a nucleocapsid protein, covalently linked to a protein of interest selected from the group consisting of a cytotoxic enzyme, an interferon, a tumor suppressor, a recombinase, a hormone, and a stem cell transcription factor;
- a fusogenic protein having reduced ligand-binding activity;
- and a nuclear localization signal (NLS) comprising at least a portion of SEQ ID NO:
- 1 or SEQ ID NO:
- 2.
A kit comprising an isolated nucleic acid encoding a VLP comprising:
- a Gag fusion protein comprising a matrix protein, a capsid protein, a nucleocapsid protein, covalently linked to a protein of interest selected from the group consisting of a cytotoxic enzyme, an interferon, a tumor suppressor, a recombinase, a hormone, and a stem cell transcription factor;
- a fusogenic protein having reduced ligand-binding activity;
- and a nuclear localization signal (NLS) comprising at least a portion of SEQ ID NO:
- 1 or SEQ ID NO:
- 2.
