Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit (which contains the 18S rRNA and 33 ribosomal proteins).

A ribosomal protein (r-protein or rProtein [1] [2] [3]) is any of the proteins that, in conjunction with rRNA, make up the ribosomal subunits involved in the cellular process of translation. E. coli, other bacteria and Archaea have a 30S small subunit and a 50S large subunit, whereas humans and yeasts have a 40S small subunit and a 60S large ...
Overview of eukaryotic messenger RNA (mRNA) translation Translation of mRNA and ribosomal protein synthesis Initiation and elongation stages of translation involving RNA nucleobases, the ribosome, transfer RNA, and amino acids The three phases of translation: (1) in initiation, the small ribosomal subunit binds to the RNA strand and the initiator tRNA–amino acid complex binds to the start ...
Ribosomopathies are congenital human disorders resulting from defects in ribosomal protein or rRNA genes, or other genes whose products are implicated in ribosome biogenesis. [39] Examples include X-linked Dyskeratosis congenita (X-DC) , [ 40 ] Diamond–Blackfan anemia , [ 41 ] Treacher Collins syndrome (TCS) [ 41 ] [ 42 ] and Shwachman ...
Cancer cells have irregularly shaped, large nucleoli, which may correspond ribosomal gene transcription up-regulation, and hence high cell proliferation. Oncogenes, like c-Myc, can upregulate rDNA transcription in a direct and indirect fashion. Tumor suppressors like Rb and p53, on the other hand, can suppress ribosome biogenesis. Additionally ...
Ribosomally synthesized and post-translationally modified peptides (RiPPs), also known as ribosomal natural products, are a diverse class of natural products of ribosomal origin. [1] Consisting of more than 20 sub-classes, RiPPs are produced by a variety of organisms , including prokaryotes , eukaryotes , and archaea , and they possess a wide ...
A later study that documented a variety of unexpected aberrant mRNA species arising from reporter plasmids revealed that splice acceptor sites can mimic both IRES and promoter elements in tests employing such plasmids, further highlighting the need for caution in the interpretation of reporter assay results in the absence of careful RNA analysis.
