Tagging and Fusion Proteins01:24

Tagging and Fusion Proteins

8.7K
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from the other proteins in the cell. This is achieved by overexpressing the specific gene in a suitable host to produce large quantities of the target protein. A tag or label is recombined with the gene to produce a fusion protein containing the target protein and the tag. The tags on these fusion proteins can then be used for easy detection and...

Antigens Involved in Adaptive Immunity

1.9K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Area of Science:

  • Molecular Biology
  • Biochemistry
  • Cell Biology

Background:

  • Protein tagging is crucial for various biological techniques, including affinity purification and live-cell fluorescence detection.
  • Current protein tags can interfere with or abolish the native function of the target protein, limiting their utility.

Purpose of the Study:

  • To introduce and characterize a novel set of small, innocuous protein tags (inntags).
  • To provide alternative tagging solutions that minimize interference with endogenous protein function.

Main Methods:

  • Development and characterization of a new class of small protein tags.
  • Assessment of the impact of these tags on native protein function through various biological assays (details not specified in abstract).

Main Results:

  • Successful design and characterization of small, innocuous protein tags (inntags).
  • These inntags are expected to have minimal impact on protein function compared to traditional tags.

Conclusions:

  • The developed inntags offer a promising alternative for protein tagging applications.
  • These tags are anticipated to be valuable tools across diverse biological techniques, enhancing experimental reliability.
