Overexpression of the mitochondrial ribosomal protein S18-2 in the invasive breast carcinomas.
Buchynska LG, et al. Exp Oncol 2018. PMID 30593750
BACKGROUND: Recent studies allow to consider the mitochondrial ribosomal protein S18-2 (MRPS18-2, S18-2) as a potential oncoprotein, which suggests the need for further characterization of its expression in tumors of different genesis including breast cancer (BC). ...

Mitochondrial ribosomal protein S18-2 evokes chromosomal instability and transforms primary rat skin fibroblasts.
Darekar SD, et al. Oncotarget 2015. PMID 26023799 Free PMC article.
We have shown earlier that overexpression of the human mitochondrial ribosomal protein MRPS18-2 (S18-2) led to immortalization of primary rat embryonic fibroblasts. ...

Mitochondrial ribosomal protein S18-2 is highly expressed in endometrial cancers along with free E2F1.
Mints M, et al. Oncotarget 2016. PMID 26959119 Free PMC article.
Histopathological diagnosis and imaging techniques for EC are limited, thus new prognostic markers are needed to offer patients the best treatment and follow-up.In the present paper we showed that the level of mitochondrial ribosomal protein MRPS18-2 (S18-2) increased in EC compared with the normal endometrium and hyperplasia, based on a study of 42 patient biopsies. ...

S18 family of mitochondrial ribosomal proteins: evolutionary history and Gly132 polymorphism in colon carcinoma.
Mushtaq M, et al. Oncotarget 2016. PMID 27489352 Free PMC article.
S18 family of mitochondrial ribosomal proteins (MRPS18, S18) consists of three members, S18-1 to -3. Earlier, we found that overexpression of S18-2 protein resulted in immortalization and eventual transformation of primary rat fibroblasts. ...Moreover, the evolutionarily conserved residue, Gly132 of S18-2, shows genetic polymorphism in colon adenocarcinomas that was confirmed by direct DNA sequencing.Concluding, S18 family represents the yet unexplored important mitochondrial ribosomal proteins....

S6:S18 ribosomal protein complex interacts with a structural motif present in its own mRNA.
Matelska D, et al. RNA 2013. PMID 23980204 Free PMC article.
Prokaryotic ribosomal protein genes are typically grouped within highly conserved operons. In many cases, one or more of the encoded proteins not only bind to a specific site in the ribosomal RNA, but also to a motif localized within their own mRNA, and thereby regulate expression of the operon. In this study, we computationally predicted an RNA motif present in many bacterial phyla within the 5' untranslated region of operons encoding ribosomal proteins S6 and S18. ...

The primary structure of rat ribosomal protein S18.
Chan YL, et al. Biochem Biophys Res Commun 1991. PMID 1872840
The amino acid sequence of the rat 40S ribosomal subunit protein S18 was deduced from the sequence of nucleotides in a recombinant cDNA. ...Rat S18 is identical to mouse S18 (also referred to as KE3) and is related to Escherichia coli S13 and to other S13-like ribosomal proteins from Bacillus subtilis, from Bacillus stearothermophilus, and from plant mitochondria (Nicotiana tabacum and Zea mays)....

Zinc regulates a switch between primary and alternative S18 ribosomal proteins in Mycobacterium tuberculosis.
Prisic S, et al. Mol Microbiol 2015. PMID 25858183 Free PMC article.
The Mycobacterium tuberculosis genome encodes five putative 'alternative' ribosomal proteins whose expression is repressed at high Zn(2+) concentration. ...We further demonstrate that both S18 proteins interact with ribosomal protein S6, a committed step in ribosome biogenesis. Zn(2+) is absolutely required for the S18-1/S6 interaction while it is dispensable for S18-2/S6 dimer formation. ...

Crystal structure of RimI from Salmonella typhimurium LT2, the GNAT responsible for N(alpha)-acetylation of ribosomal protein S18.
Vetting MW, et al. Protein Sci 2008. PMID 18596200 Free PMC article.
The three ribosomal proteins L7, S5, and S18 are included in the rare subset of prokaryotic proteins that are known to be N(alpha)-acetylated. The GCN5-related N-acetyltransferase (GNAT) protein RimI, responsible for the N(alpha)-acetylation of the ribosomal protein S18, was cloned from Salmonella typhimurium LT2 (RimI(ST)), overexpressed, and purified to homogeneity. ...

Reduced dosage of genes encoding ribosomal protein S18 suppresses a mitochondrial initiation codon mutation in Saccharomyces cerevisiae.
Folley LS and Fox TD. Genetics 1994. PMID 8070651 Free PMC article.
Suppression and cold sensitivity resulted from inactivation of the gene product of RPS18A, one of two unlinked genes that code the essential cytoplasmic small subunit ribosomal protein termed S18 in yeast. ...Yeast S18 is homologous to the human S11 (70% identical) and the Escherichia coli S17 (35% identical) ribosomal proteins. This highly conserved family of ribosomal proteins has been implicated in maintenance of translational accuracy and is essential for assembly of the small ribosomal subunit. ...
