Summary
Hedgehog (Hh) signaling proteins are crucial for development and are regulated by post-translational modifications. These modifications impact Hh protein processing, affecting cell signaling and gradient establishment.
Area of Science:
- Developmental Biology
- Cell Signaling
- Molecular Biology
Background:
- Hedgehog (Hh) proteins are essential secreted signaling molecules.
- Hh signaling regulates the development of numerous tissues and organ systems.
- The biological activity of Hh proteins is modulated by post-translational modifications.
Purpose of the Study:
- To review the current understanding of Hh signaling mechanisms.
- To elucidate how Hh gradients are established.
- To explain the transduction of Hh signals.
Main Methods:
- Review of existing literature and recent data.
- Analysis of post-translational modification processes.
- Examination of Hh protein processing, trafficking, and signaling.
Main Results:
- Hh protein processing involves intramolecular cleavage, lipidation (cholesterol/palmitate), and multimerization.
- These processing steps critically influence Hh protein trafficking, potency, and signaling range.
- Recent data shed light on the mechanisms governing Hh gradient formation and signal transduction.
Conclusions:
- Post-translational modifications are key regulators of Hh protein function.
- Understanding Hh processing is vital for comprehending developmental signaling.
- This review synthesizes current knowledge on Hh signaling dynamics.

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

03:14Notch 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 until 1985...

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...

01:22Microtubules 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...
