About the nucleic acid binding protein in eukaryotes the bacterial porin ProteinK porin ProteinK is a human protein found in the cell nucleus that binds to pre messenger RNA mRNA as a component of heterogeneous ribonucleoprotein particle s. The simian homology biology homolog is known as protein H16 . Both proteins bind to single stranded DNA as well as to RNA and can stimulate the activity of RNA polymerase II , the protein responsible for most transcription genetics gene transcription . The relative affinities of the proteins for DNA and RNA vary with solution conditions and are inversely correlated, so that conditions promoting strong DNA binding result in weak RNA binding. ref name Gaillard Gaillard C, Cabannes E, Strauss F. 1994 .

GeneExpression Programming GEP is an evolutionary algorithm that evolves populations of computer program s in order to solve a user defined problem. GEP has similarities, but is distinct from, the evolutionary computational method of genetic programming . In genetic programming the individuals comprising a population are typically symbolic s expressionexpression trees however, the individuals comprising a population of GEP are encoded as linear chromosome s, which are then translated into s expressionexpression trees . The important difference is that the recombination operators of genetic programming operate directly on the tree structure e.g. swapping sub trees , whereas the recombination operators of geneexpression programming operate directly on the linear encoding i.e. before it is translated into a tree . As such, after recombination, the modified portions of the resulting expression trees often bear little semblance to their direct ancestors. The expression trees are themselves computer programs evolved to solve a particular problem and are selected according to their performance fitness in solving the problem at hand. After repeated iteration, populations of such computer programs will ideally discover new traits and become better adapted to a particular selection environment. The desired endpoint of the algorithm is that a good solution has been evolved by the evolutionary process.

The Wellcome Trust Centre for Gene Regulation and Expression , located within the University of Dundee , pioneers new approaches in the field of geneexpression and chromosome biology. Previously part of the Dundee Biocentre and receiving significant Wellcome Trust funding from 1995 onwards, it was awarded Wellcome Trust Centre status in 2008. Professor Angus Lamond is the Centre s Director. The Centre aims to enhance our understanding of how genes are regulated at both the single cell and whole organism level. Researchers use a wide range of advanced techniques, including live cell fluorescent imaging disambiguation needed date November 2011 and mass spectrometry based proteomics , to explore the functions of key proteins and molecular mechanisms in cell biology. Research and discoveries Live cell imaging and proteomic studies have allowed researchers at the Centre to gain fresh understanding of protein function and cell behaviour. The Centre is studying many aspects of the cell cycle , including the way in which chromosomes replicate and separate during cell division and how DNA damage is detected. Failure of these events can lead to major faults within a genome , potentially leading to the rise of cancerous cells. The Centre is also investigating how DNA is tightly wound and compacted so that it can fit into the nuclei of eukaryotic cells, as well as the protein DNA complexes that are involved in this packaging. The controlled unravelling of DNA is an important step in the regulation of gene function. Researchers Researchers at the Centre include Professor Angus Lamond a Wellcome Principal Research Fellow, studies the composition and function of organelles and multiprotein complexes ref cite journal pages 1153 9 doi 10.1002 pmic.201000548 title Mass spectrometry based ...

The ROSE element is an RNA thermometer that negatively regulates heat shock geneexpression . The secondary structure is thought to be altered by temperature, thus it is an RNA thermometer. This structure blocks access to the Shine Dalgarno sequence ribosome binding site at normal temperatures. During heat shock however, the structure changes freeing the ribosome binding site and allowing expression to occur. ref cite journal last Nocker first A coauthors Hausherr T, Balsiger S, Krstulovic NP, Hennecke H, Narberhaus F year 2001 title A mRNA based thermosensor controls expression of rhizobial heat shock genes journal Nucleic Acids Res volume 29 pages 4800&ndash 4807 pmid 11726689 doi 10.1093 nar 29.23.4800 issue 23 pmc 96696 ref ref cite journal last Balsiger first S coauthors Ragaz ... geneexpression ROSE element DEFAULTSORT Repression Of Heat Shock GeneExpression Rose Element Category ...
