Authentic ScRlg1p interacts with both HAC1u and HAC1i mRNAs. Logarithmically growing yeast cells with no (wt), KAP95-TAP (KAP95-TAP), or ScRLG1-protein A (ScRLG1-prot. A) gene integrated into the chromosome were treated with (+Tm) or without (−Tm) Tm for 30 min and then were analyzed by CLIP. After cross-linking with 1.0% formaldehyde for 30 min, extracts were prepared and subjected to IP with IgG-Sepharose. Immunoprecipitated HAC1 mRNAs (A) and ACT1 mRNA (B) were amplified by RT-PCR with primers represented as thick arrows in schematic drawings of the genes. T, total extract; FT, flow through; RNase IP, immunoprecipitate from the extract treated with RNase A; IP, immunoprecipitate. In A, recovery of HAC1 mRNAs (HAC1u in the absence of Tm and HAC1i in the presence of Tm) in the immunoprecipitates was quantified by semiquantitative RT-PCR with a microchip electrophoresis system. The values were obtained from three independent IPs.
