      N-terminal acetylation (NTA) is a common modification of eukaryotic proteins occurring on more than 50 and 80% of yeast and human cytosolic proteins, respectively is catalysed by ribosome Cited by:   Translation of the coding potential of a messenger RNA into a protein molecule is a fundamental process in all living cells and consumes a large fraction of metabolites and energy resources in growing cells. Moreover, translation has emerged as an important control point in the regulation of gene expression. At the level of gene regulation, translational control is utilized to Cited by:

      The NRT1 family of nitrate transporters. Unlike NO 3 − reduction, the molecular genetics of NO 3 − uptake had been hampered by the fact that no uptake mutants were known in plants for sometime except for chl1 in Arabidopsis (in the new nomenclature the gene is called AtNRT).Ironically, this was the first chlorate-resistant mutant ever identified in plants, and Cited by: The effects of lithium on translation initiation in yeast are suppressed by eIF4A overexpression (Montero-Lomeli et al., ), eIF4A functions in germ line stem cell renewal via effects on BAM (Bag-of-marbles) in the Drosophila ovary (Shen et al., ), eIF4A is a target for the inhibitory BC1 RNA in neurons (Lin et al., ) and a lipid Cited by:

    FIGURE 6: Differences in the 5′ UTR between the translationally altered gene sets and an overlap in up-regulated genes following glucose and amino acid starvation were observed. (A) Analysis of the 5′ UTR between the translationally up-regulated and unaffected data sets reveals a statistically relevant reduction in the GC content. One of the kingdom level taxa proposed by Cavallier-Smith which consists of the most ancient unicellular eukaryotes with a nucleus and rod shaped chromosome but no mitochondria or plastid, thus believed to be the intermediate stage between prokaryotes and eukaryotes. They are also used as evidence for the evolution of nucleus before the organelles.

Modern biology is rooted in an understanding of the molecules within cells and of the interactions between cells that allow construction of multicellular organisms.

The more we learn about the structure, function, and development of different organisms, the more we recognize that all life processes exhibit remarkable similarities. Molecular Cell Biology concentrates on the Cited by:   Retrograde signals emanate from the DNA-containing cell organelles (plastids and mitochondria) and control the expression of a large number of nuclear genes in response to environmental and developmental cues.

Previous studies on retrograde signaling have mainly analyzed the regulation of nuclear gene expression at the transcript level. To determine the Cited by: 1. An overlapping gene is a gene whose expressible nucleotide sequence partially overlaps with the expressible nucleotide sequence of another gene.

In this way, a nucleotide sequence may make a contribution to the function of one or more gene products.

Overprinting refers to a type of overlap in which all or part of the sequence of one gene is read in an alternate reading frame from. The conserved eukaryotic translation initiation factor 5B, eIF5B, is a GTPase that acts late in translation initiation.

We found that an Arabidopsis thaliana mutant sensitive to hot temperatures 3 (hot), which behaves as the wild type in the absence of stress but is unable to acclimate to high temperature, carries a missense mutation in the eIF5B1 gene (At1g), Cited by: Synthesis of the translational apparatus is regulated at the translational level Higher eukaryotes have devised a simple mechanism initiation factor genes are among the translationally Author: Oded Meyuhas.

The expression of many genes in embryo development of eukaryotes is regulated at the translational level by vari- ety of mechanisms [2]. The individual templates differ. Yafang Shao, Jinsong Bao, in Rice (Fourth Edition), Regulatory genes.

Regulatory genes influence the intensity and tissue specific pattern of phenolics accumulation and generally regulate expression of different structural genes at transcription level (Hichri et al., ).Two kinds of regulatory genes, particularly for maize and orthologs in other plant species, act as.

The biological importance of manganese lies in its function as a key cofactor for numerous metalloenzymes and as non-enzymatic antioxidant. Due to these two essential roles, it appears evident that disturbed manganese homeostasis may trigger the development of pathologies in humans.

In this context, yeast has been extensively used over the last decades to gain insight Author: Louise Thines, Antoine Deschamps, Jiri Stribny, Pierre Morsomme. In higher eukaryotes deposition of m 5 C modification is carried out by RNA methyltransferases NSun2 and DNMT2 [38,39,40].

NSun2 is a nucleoler protein and encoded by highly conserved family of NOL1/NOP2/Sun domain (NSun) containing RNA methyltransferase genes, which comprises of six members including NSun2 or Misu [39,41].Cited by: 1. In a recent book by Ptashne and Gann (Genes and Signals, Cold Spring Harbor Press, ), it is argued that you can and through a very simple mechanism.

It must be clear that to activate gene transcription, several transcription factor proteins must assembly at the promoter before RNA polymerase can transcribe a gene. These two phases correspond to key stages of the seed‐to‐seedling transition.

Interestingly, the two shifts are regulated by distinct mechanisms, as is shown by the different trends in the ratios of transcription and translation, and by different sequence features of the mRNAs identified as translationally regulated (Bai et al., ).Cited by: Schizosaccharomyces pombe or fission yeast has been called micromammal due to the potential application of the knowledge derived from the yeast in the physiology of higher eukaryotes.

Fission yeast has been consolidated as an excellent model for the study of highly conserved cellular processes.

In eukaryotes, while there are a few DNA repair proteins that are transcriptionally regulated (for example, PCNA and DNA polymerase β), most DNA repair is regulated at the level of post-translational modifications such as phosphorylation, acetylation, protein complex formation, as well as monoubiquitination, polyubiquitination, sumoylation Cited by: 2.

Goldman, in Encyclopedia of Genetics, As there is a vast difference in how tissue-specific in contrast to housekeeping genes must be regulated, it is not surprising that the promoters of these genes differ as well. Most housekeeping genes utilize a promoter lacking the common TATA and CAAT boxes, and having instead a series of GC boxes (consensus.

The control of mRNAs encoding cell cycle regulatory proteins in early development has been extensively characterized in lower and higher eukaryotes in the last decade; this research has uncovered one of the best-understood mRNA-specific translational regulators, cytoplasmic polyadenylation element binding protein (CPEB), the major subject of Author: Nancy Standart.

Eukaryotic translation initiation factor 3 (eIF3) plays a central role in translation initiation and consists of five core (conserved) subunits present in both budding yeast and higher eukaryotes.

Higher eukaryotic eIF3 contains additional (noncore or nonconserved) subunits of poorly defined function, including sub-unit h (eIF3h), which in.*Edited by Thomas Blumenthal.

In addition, we show that the PRR7 protein is phosphorylated in a circadian regulated manner and that its levels are post‐translationally regulated by both diurnal and circadian mechanisms.

The Arabidopsis circadian oscillator is therefore likely to be entrained to light/dark cycles both through transcriptional and post‐transcriptional Cited by:
