Research Abstract

Although autosomal dominant retinitis pigmentosa (AdRP) is a tissue specific disease, disease associated mutations were found in several constitutive splicing factors consisting the spliceosome as well as genes in photo signal transduction pathway. To elucidate the mechanism how abnormality of general splicing factors triggers AdRP, we tried to detect the effect of the mutations on the cellular splicoeosme levels using a newly developed reporter. The reporter experiment suggested that the cell may regulate the spliceosome level to adjust the surrounding environment.
