Gene expression is regulated by factors both extrinsic and intrinsic to the cell. Cell-extrinsic factors that regulate expression include environmental cues, such as small molecules, secreted proteins, temperature, and oxygen. These cues can originate from other cells within the organism, or they can...

Several environmental factors modify the expression of S. aureus virulence genes. This report shows that the expression of spa (virulence gene encoding the cell-wall-associated protein A) is down-regulated by high osmolarity (1 M NaCl, 1 M KCl or 1 M sucrose) in the wild-type strain and ...
This is why gene expression is regulated. How exactly are genes regulated? Let’s find out. Suggested Videos Regulation Of Gene Expression Protein synthesis begins at transcription, ends at translation and involves multiple steps. Therefore, regulation of gene expression can happen at any of these ...
Homeostasis of protein concentrations in cells is crucial for their proper functioning, requiring steady-state concentrations to be stable to fluctuations. Since gene expression is regulated by proteins such as transcription factors (TFs), the full set of proteins within the cell constitutes a large ...
Protein A gene expression is regulated by DNA supercoiling which is modified by the ArlS–ArlR two-component system of Staphylococcus aureus Bacterial pathogens such as Staphylococcus aureus undergo major physiological changes when they infect their hosts, requiring the coordinated regulation of...

An expression system for transforming E coll with a nucleic acid molecule of interest has an operator sequence of a cmt operon operatively linked to a promoter for the operator, and, a repressor sequence from a cym operon operatively linked to a promoter for the repressor. The expression system...
Regulating Gene Expression Reviewing Vocab… GENE: a segment of DNA that codes for a particular protein/trait An expressed gene is one that is being transcribed (i.e. it is turned to the “on” position and is being used to make proteins!) A repressed gene is one that is not being tra...
