| Outline of Final Research Achievements |
It has been reported that nonsense mutation of transcriptional repressor RP58 is found in the patients of intellectual disability, and the expression of RP58 is reduced in aged prefrontal cortex. Therefore, we raise the hypothesis that the quantity of RP58 is important for brain function.
To examine the hypothesis, we generated the mice, in which RP58 expression is reduced. The RP58 hetero mice (RP58+/-) show the abnormal behaviors with little abnormality of brain formation. The mice, in which the expression of RP58 is reduced to one-third, shows more sever abnormal behavior and abnormal brain formation. These results indicate that quantitative expression of RP58 is involved in behavior and brain formation.
