NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.7K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Co-activators and Co-repressors

7.4K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

5.7K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

6.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Protein Networks02:26

Protein Networks

4.0K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.6K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Area of Science:

  • Systems biology
  • Molecular biology
  • Cell signaling

Background:

  • The nuclear factor kappa B (NF-κB) system regulates critical cellular functions like inflammation and proliferation.
  • Cell type-specific NF-κB dimer repertoires influence its activity.
  • Existing mathematical models address cell-specific NF-κB activities.

Purpose of the Study:

  • To synthesize a consensus mathematical model for the NF-κB multidimer system.
  • To explain cell type-specific NF-κB signaling properties.
  • To establish a knowledge base for understanding NF-κB control in health and disease.

Main Methods:

  • Developed a consensus mathematical model for the NF-κB multidimer system.
  • Analyzed cell type-specific expression of NF-κB monomers.
  • Reviewed existing mathematical models of NF-κB signaling.

Main Results:

  • The consensus model accounts for cell type-specific NF-κB dimer repertoires and their activation.
  • Cell type-specific NF-κB signaling emerges from differential monomer expression.
  • The model integrates diverse NF-κB activities and cross-talk.

Conclusions:

  • Cell type-specific NF-κB signaling is largely an emergent property of monomer expression levels.
  • The consensus model provides a framework for understanding NF-κB regulation.
  • This approach can be applied to other pleiotropic signaling systems.
