Theiler's virus-specified polypeptides made in BHK-21 cells. 1984

H L Lipton, and E J Rozhon, and D Black

This study was initiated to determine whether the Theiler's murine encephalomyelitis viruses (TMEV) use the same strategy of gene expression as other picornaviruses. The precursor-product relationships apparent from pulse-chase experiments indicated that the virus-specified polypeptides of the GDVII strain are generated by post-translational cleavages. Pactamycin mapping experiments also showed a gene order for GDVII virus similar to that derived for other picornaviruses by this technique. Finally, six other TMEV induced species of polypeptides similar to those of GDVII virus, but there were minor differences in some of their electrophoretic mobilities.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D010142	Pactamycin	Antibiotic produced by Streptomyces pactum used as an antineoplastic agent. It is also used as a tool in biochemistry because it inhibits certain steps in protein synthesis.
D010452	Peptide Biosynthesis	The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.	Biosynthesis, Peptide
D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D011499	Protein Processing, Post-Translational	Any of various enzymatically catalyzed post-translational modifications of PEPTIDES or PROTEINS in the cell of origin. These modifications include carboxylation; HYDROXYLATION; ACETYLATION; PHOSPHORYLATION; METHYLATION; GLYCOSYLATION; ubiquitination; oxidation; proteolysis; and crosslinking and result in changes in molecular weight and electrophoretic motility.
