Notch Signaling Pathway03:14

Notch Signaling Pathway

5.8K
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...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.9K
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...

Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

5.7K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

6.3K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Intracellular Signaling Cascades01:24

Intracellular Signaling Cascades

51.3K
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

Microtubules in Signaling01:22

Microtubules in Signaling

2.0K
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...

Area of Science:

  • Neurobiology
  • Molecular Biology
  • Genetics

Background:

  • Cerebral cavernous malformations (CCMs) are neurovascular lesions linked to mutations in KRIT1, CCM2, or CCM3 genes.
  • These mutations disrupt CCM protein complex function, affecting cell adhesion, contractility, and gene expression.
  • CCMs can lead to serious neurological conditions like hemorrhage, stroke, and epilepsy.

Purpose of the Study:

  • To review current knowledge on CCM protein signaling pathways.
  • To explore the molecular mechanisms underlying CCM pathogenesis.
  • To identify key signaling pathways involved in CCM disease.

Main Methods:

  • Literature review of recent advances in CCM research.
  • Analysis of protein structures and interactions.
  • Focus on RhoA-ROCK, MEKK3-MEK5-ERK5-KLF2/4, and cell junctional signaling pathways.
  • Consideration of ICAP1-β1 integrin and cdc42 signaling.

Main Results:

  • CCM proteins form a complex that modulates critical cellular processes.
  • Specific signaling pathways (RhoA-ROCK, MEKK3, etc.) are implicated in CCM development.
  • Emerging evidence links these pathways to disease pathology.

Conclusions:

  • Understanding CCM protein signaling is vital for deciphering disease mechanisms.
  • Further research into subcellular localization's role in CCM protein activity is needed.
  • This review consolidates current knowledge and highlights future research directions.
