Physiological Function Of Fus: An Rna Binding Protein In Motor Neuron Disease, Liuqing Yang

Theses and Dissertations--Molecular and Cellular Biochemistry

FUS is an RNA binding protein implicated in the motor neuron disease— amyotrophic lateral sclerosis (ALS, also called Lou Gehrig’s disease). ALS is a fatal neurodegenerative disease characterized by progressive motor neuron death. Mutations in the FUS gene cause about 4% of familial ALS (FUS ALS). Mutated FUS protein mislocalizes from the motor neuron nucleus to the cytoplasm and forms inclusions in the cytoplasm. It is unclear how FUS mislocalization induces motor neuron dysfunction and degeneration. This dissertation research was designed to investigate the physiological functions of FUS in the nucleus, with a purpose to shed light on the pathogenesis …
