Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...
Reporter Genes02:11

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
Commonly used reporter...

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Pharmacology

Background:

  • Mammalian cell lines are crucial for studying protein function and drug discovery.
  • Efficient generation of stable cell lines expressing specific genes of interest (GOI) is essential for reproducible research.
  • Existing methods for generating stable cell lines can be time-consuming and lack precise control over gene expression.

Purpose of the Study:

  • To describe a method for generating stable mammalian cell lines with controlled expression of a gene of interest (GOI).
  • To highlight the utility of the Flp-In™ T-Rex™ system for inducible and stable protein expression.
  • To demonstrate the application of these cell lines in studying G protein-coupled receptor (GPCR) pharmacology.

Main Methods:

  • Utilizing the Flp-In™ system for site-specific genomic integration of a GOI.
  • Employing the Flp-In™ T-Rex™ system for tetracycline-inducible control of gene expression.
  • Generating isogenic stable cell lines ensuring consistent protein expression levels.

Main Results:

  • The Flp-In™ system enables easy and efficient generation of mammalian cell lines for protein expression.
  • Isogenic cell lines provide constant protein expression across the cell population.
  • The Flp-In™ T-Rex™ system allows for controlled protein expression via a small molecule inducer.

Conclusions:

  • Stable, inducible mammalian cell lines can be readily generated using the Flp-In™ T-Rex™ system.
  • These cell lines are valuable tools for investigating receptor pharmacology, signaling pathways, and protein oligomerization.
  • The system offers a robust platform for reproducible studies in molecular and cell biology.
