Carbodiimide-induced protein--RNA crosslinking in mammalian ribosomal subunits
Abstract:
RNA--protein interactions in the 60 S subunits of rat liver ribosomes were studied using 1-ethyl-3-dimethylaminopropyl carbodiimide (EDC) under conditions which neither changed the sedimentation coefficient of subunits nor the intactness of their rRNA. EDC induced RNA--protein and protein--protein crosslinkings. Proteins crosslinked to 28 S RNA were identified by two-dimensional gel electrophoreses as L17, L19, L23a and L37a, shown to react with 28 S RNA when using a low dose of UV radiation. Attempts have also been made to use EDC for the studies of RNA--protein interactions in 40 S ribosomal subunits.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
