Summary
Nuclear factor kappa B (NF-κB) transcription factors regulate immunity and stress. Their activation involves complex signaling pathways and regulatory mechanisms for cell-specific responses.
Area of Science:
- Molecular Biology
- Cell Signaling
- Immunology
Background:
- Nuclear factor kappa B (NF-κB) transcription factors are key regulators of essential cellular processes.
- NF-κB activation mediates diverse transcriptional programs in response to various stimuli.
- The activity of NF-κB is tightly controlled by intricate regulatory networks.
Purpose of the Study:
- To elucidate the regulatory mechanisms governing NF-κB-dependent transcription.
- To understand the crosstalk between NF-κB signaling and other cellular pathways.
- To highlight the importance of context-specific NF-κB functions.
Main Methods:
- Analysis of NF-κB signaling pathways.
- Investigation of regulatory mechanisms (positive and negative feedback loops).
- Study of crosstalk with other signaling networks.
Main Results:
- NF-κB activation is a central hub for multiple stimuli.
- Complex regulatory mechanisms ensure precise control of NF-κB.
- Significant crosstalk exists between NF-κB and other signaling pathways.
Conclusions:
- NF-κB transcription factors play a critical role in immunity, stress, apoptosis, and differentiation.
- The precise biological functions of NF-κB are shaped by intricate regulatory networks and pathway crosstalk.
- Cell type and context are crucial determinants of NF-κB-mediated responses.

02:26NF-κB-dependent Signaling Pathway
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.

01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

02:04Co-activators and Co-repressors
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...
01:07MAPK Signaling Cascades
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...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
