Retinitis pigmentosa mutations of SNRNP200 enhance cryptic splice-site recognition.

Abstract excerpt

Mutations in SNRP200 gene cause autosomal-dominant retinal disorder retinitis pigmentosa (RP). The protein product of SNRNP200 is BRR2, a DExD/H box RNA helicase crucial for pre-mRNA splicing. In this study, we prepared p.S1087L and p.R1090L mutations of human BRR2 using bacterial artificial chromosome recombineering and stably expressed them in human cell culture. Mutations in BRR2 did not compromise snRNP...
