Cell recoding molecules. Medical search. Frequent questions

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding-a genetic editing method cells use to expand the number of proteins assembled from a single DNA code. (cometaasmme.org)
By making small alterations in introns during evolution, different insects conserved the basic RNA code for making important proteins, but developed a way to tweak the resulting nerve cell protein's function in a species-specific manner. (cometaasmme.org)
RNA recoding lets cells generate an array of proteins from a single DNA sequence, each with a slightly different function. (cometaasmme.org)
Producing different proteins in a cell at once could let organisms fine tune biological processes with extreme precision-a level of flexibility the DNA code doesn't afford. (cometaasmme.org)
Genetics is digital," says Reenan, adding "Editing changes digital to analog," letting cells "dial up" the exact amounts of altered proteins required at any given time or place. (cometaasmme.org)
This is where the Marie Curie - Intra European Fellowship project MazProTec (number 298326, "Two-Step-Strategy towards an Orthogonal Bio-System") tried to introduce a novel principle into biocatalyst production, exploiting the ability of regular cells of the bacterium Escherichia coli to decide on a cell-wide scale which proteins to make and which not. (europa.eu)
In the appropriate situation, MazF becomes active and prevents most mRNA molecules from becoming translated, while ACA-free mRNAs continue to be read out into proteins. (europa.eu)
In MazProTec, the goal was to use this mechanism to force the cell at one specific point in time to dedicate its resources entirely to the production of desired proteins, thus leading to cells (highly) enriched with specific enzymes. (europa.eu)
Under this hypothesis, any model for the emergence of the genetic code is intimately related to a model of the transfer from ribozymes (RNA enzymes) to proteins as the principal enzymes in cells. (mercinewyork.com)
This doesn't matter in RNA, since new RNA copies can be produced from DNA at any time, and most RNA molecules are intentionally destroyed by the cell a short time after they're produced so that the cell does not waste resources producing unneeded proteins from old RNA molecules. (mercinewyork.com)
1. The cell biology of MHC class I-restricted antigen processing and presentation: My laboratory continues to explore the forces that drive the extremely rapid MHC class I-restricted presentation of both cytosolic and endoplasmic reticulum-targeted proteins, and how differential processing could impact both the induction and effector phases of CD8+ T cell responses. (upenn.edu)
2. The cell biology of MHC class II-restricted antigen processing and presentation: A generally accepted paradigm in fundamental immunology is that CD4+ T cells recognize peptides derived from exogenous (internalized) sources of antigen while CD8+ recognize peptides derived from endogenous sources of antigen (generally, proteins synthesized within the antigen-presenting cell).
