Fig. 5. MEG3 physically interacts with SMO protein.

a The overall interaction propensity of MEG3 and SMO protein was predicted by catRAPID. b Predicted interaction between MEG3 (nucleotide positions 0–1200 nt) and SMO protein (amino acid residues 0–720). c RIP experiments were performed using SMO antibody in primary HSCs at Day 0. qRT-PCR was performed to detect pulled-down MEG3. hnRNP-K antibody and IgG were used as positive and negative controls, respectively. d SMO asscociated MEG3 was detected by regular RT-PCR. e Mapping the SMO interaction region of MEG3. Biotinylated RNAs corresponding to different fragments of MEG3 or its antisense sequences (red line) were co-incubated with cell lysates and associated SMO proteins were detected by immunoblotting
