| abstractText | Mutations in Als2 gene cause several autosomal recessive forms of motor neuron diseases including Juvenile Amyotrophic Lateral Sclerosis (JALS), Juvenile Primary Lateral Sclerosis (PLSJ) and Infantile-onset Ascending Hereditary Spastic Paralysis (IAHSP). To find novel protein-protein interactions of Als2 protein we performed a yeast two hybrid screen and fished out the Ubiquitously Expressed Transcript (UXT) protein. UXT is a novel gene encoding for an alpha-class prefoldin type chaperone which acts as a co-activator for various transcriptional factors such as Nf-kappaB and AR. The interaction between Als2 and UXT was confirmed by co-immunoprecipitation. Co-localization between endogenous Als2 and UXT was mainly found in the cytoplasm of neuronal Neuro2a cells with immunofluorescence microscopy. Cell cycle arrest of Neuro2a cells showed that Als2 and Uxt transcriptional levels are synchronously changing. Our results suggest that Als2 is a binding partner of Uxt and Als2/Uxt interaction could be important for the activation of Nf-kappaB pathway. These results provides basis for future research to investigate the role of Nf-kappaB pathway in the development of motor neuron diseases. |
