Abstract
Abstract Ribosomal proteins are involved in many cellular processes through interactions with various RNAs. Here, applying the photoactivatable-ribonucleoside-enhanced cross-linking and immunoprecipitation approach to HEK293 cells overproducing ribosomal protein (rp) eS1, we determined the products of RNU5A-1 and RNU11 genes encoding U5 and U11 snRNAs as the RNA partners of ribosome-unbound rp eS1. U11 pre-snRNA-associated rp eS1 was revealed in the cytoplasm and nucleus where rp eS1-bound U11/U12 di-snRNP was also found. Utilizing recombinant rp eS1 and 4-thiouridine-containing U11 snRNA transcript, we identified an N-terminal peptide contacting the U-rich sequence in the Sm site-containing RNA region. We also showed that the rp eS1 binding site on U11 snRNA is located in the cleft between stem-loops I and III and that its structure mimics the respective site on the 18S rRNA. It was found that cell depletion of rp eS1 leads to a decrease in the splicing efficiency of minor introns and to an increase in the level of U11 pre-snRNA with the unprocessed 3′ terminus. Our findings demonstrate the engagement of human rp eS1 in events related to the U11 snRNA processing and to minor-class splicing. Contacts of rp eS1 with U5 snRNA in the minor pre-catalytic spliceosome are discussed.
