Modified polypeptides and uses thereof

Abstract

Provided herein are modified cyclin F polypeptides and nucleic acid molecules encoding the same. In particular, provided herein are modified cyclin F polypeptides that have increased cytoplasmic targeting compared to wild-type cyclin F polypeptides, and functional, truncated modified cyclin F polypeptides, and nucleic acid molecules encoding the same. Also provided herein is the use of the modified cyclin F polypeptides and encoding nucleic acid molecules for enhancing motor neuron survival, inhibiting motor neuron degeneration and treating neurodegenerative conditions, in particular those associated with neuronal TDP-43 proteinopathy.
