a, Enrichment analysis of proteins that were co-purified with Fc-tagged RPL22L1a (lower panel) or RPL22L1b (upper panel) and subsequently identified by LC-MS/MS. b, Enrichment analysis of mRNAs that were co-purified with Fc-tagged RPL22L1a (left panel) or RPL22L1b (right panel) and subsequently identified by RNA sequencing. c, KEGG database GSVA analysis of RNA sequencing data obtained from 157 cells overexpressing RPL22L1a, RPL22L1b or an empty vector (experiment was performed in two biological replicates). d, Enrichment analysis of proteins that were differentially present in 157 cells overexpressing RPL22L1a or RPL22L1b isoform as determined by SILAC LC-MS/MS. e, Enrichment analysis of alternative splicing events related to exon skipping (upper panel) or mutually exclusive exon inclusion (lover panel) detected in 157 cells stably expressing RPL22L1b compared to the control cells.
