Summary
Receptor tyrosine kinase (RTK) signaling controls cell behavior and development. This review explores feedback loops that regulate RTK activity, crucial for embryonic development and preventing diseases like cancer.
Area of Science:
- Developmental Biology
- Cell Signaling
- Molecular Biology
Background:
- Receptor tyrosine kinase (RTK) signaling is vital for cellular functions.
- Dysregulation of RTK signaling is implicated in congenital syndromes and cancers.
- Feedback mechanisms precisely control RTK signaling amplitude and duration.
Purpose of the Study:
- To review regulators of RTK signaling, focusing on their roles in embryonic development.
- To elucidate the mechanisms of negative and positive feedback loops in RTK signaling.
- To highlight the implications of RTK signaling dysregulation in human diseases.
Main Methods:
- Literature review of biochemical and genetic studies.
- Analysis of regulatory mechanisms tuning RTK activity and signal transduction.
- Focus on the role of RTK regulators in embryonic development.
Main Results:
- Identified diverse inhibitory mechanisms of negative feedback regulators.
- Detailed how loss of negative feedback leads to increased RTK signaling.
- Discussed positive regulators and their interplay with negative regulators in development.
Conclusions:
- Precise RTK signaling control is essential for embryonic development.
- Feedback loops, both positive and negative, are critical for guiding developmental processes.
- Understanding RTK regulation offers insights into congenital disorders and cancer pathogenesis.

19.6K
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

87.0K
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...

01:07MAPK Signaling Cascades
8.7K
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...

3.7K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

5.8K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

5.5K
Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
