Insights

Tumor necrosis factor receptor-associated factor 7 (TRAF7) is crucial for cell processes. TRAF7 alterations link to developmental disorders and cancers, necessitating further research for biomarkers and therapies.

Area of Science:

  • Molecular Biology
  • Cellular Signaling
  • Cancer Biology

Background:

  • Tumor necrosis factor receptor-associated factors (TRAFs) are key signaling proteins.
  • TRAF7, the newest TRAF, has unique E3 ubiquitin ligase activity and regulates multiple pathways.
  • TRAF7 mutations are implicated in developmental disorders and various cancers.

Purpose of the Study:

  • To comprehensively review the physiological roles of TRAF7.
  • To explore the pathophysiology of clinical conditions associated with TRAF7 alterations.
  • To identify future research directions for TRAF7-related diseases.

Main Methods:

  • Literature review of TRAF7's physiological functions.
  • Analysis of clinical data linking TRAF7 mutations/expression to diseases.
  • Synthesis of current knowledge on TRAF7's role in immunity, inflammation, apoptosis, and cancer.

Main Results:

  • TRAF7 activates MEKK3 and KLF2/4 signaling, inhibits MEK1/2 and c-Myb, and stabilizes VE-cadherins.
  • Germline TRAF7 mutations cause developmental delays and dysmorphic features (TRAF7 syndrome).
  • Somatic TRAF7 mutations are found in meningiomas, mesotheliomas, and perineuriomas; altered expression correlates with poor prognosis in liver, breast, and prostate cancers.

Conclusions:

  • TRAF7 plays diverse roles in fundamental cellular processes.
  • TRAF7 alterations are linked to significant human diseases, from developmental syndromes to cancers.
  • Further research is needed to understand TRAF7 mechanisms, identify biomarkers, and develop targeted therapies.

Microtubules in Signaling01:22

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

Interactions Between Signaling Pathways01:19

Interactions 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...

MAPK Signaling Cascades01:07

MAPK 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...

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
