Summary
Bone morphogenetic proteins (BMPs) were discovered to induce bone formation, but later found to regulate diverse biological processes. Research in Drosophila advanced understanding of BMP signaling complexity and regulation.
Area of Science:
- Molecular Biology
- Developmental Biology
- Genetics
Background:
- Bone morphogenetic proteins (BMPs) were initially identified for their bone-inducing properties.
- The discovery of Drosophila decapentaplegic (dpp) revealed BMPs' broader roles beyond skeletogenesis.
- BMP signaling is crucial in various developmental processes across species.
Approach:
- Collaborative research between Drosophila geneticists and mammalian biochemists identified key BMP pathway components.
- Genetic modifier screens in Drosophila were instrumental in discovering intracellular signal transducers.
- Comparative studies in model organisms elucidated conserved mechanisms of BMP signaling.
Key Points:
- The core BMP pathway involves a ligand, receptor, and signal transducer.
- Multiple layers of regulation ensure precise, tissue-specific BMP signaling output.
- Drosophila genetic screens identified numerous regulators of BMP signaling and related pathways.
Conclusions:
- BMP signaling, though core components are simple, exhibits remarkable versatility through complex regulatory networks.
- Decades of research have significantly advanced our understanding of BMP pathway function and regulation.
- Further investigation is needed to fully unravel the intricate complexity of BMP signaling.

7.4K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

03:14Notch Signaling Pathway
4.3K
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...

2.6K
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...

01:20The JAK-STAT Signaling Pathway
8.9K
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...

3.6K
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...

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...
