Summary
Researchers developed cilia-APEX, a new method to capture dynamic snapshots of the primary cilium proteome. This technique overcomes challenges in studying signaling within this crucial organelle during development and disease.
Area of Science:
- Cell Biology
- Molecular Biology
- Developmental Biology
Background:
- The primary cilium is vital for cellular signaling in development and disease.
- Studying the primary cilium's proteome is challenging due to its small size and dynamic signaling events.
Purpose of the Study:
- To introduce a novel technique for dynamic proteome analysis of the primary cilium.
- To overcome limitations in dissecting ciliary signaling mechanisms.
Main Methods:
- Development of the cilia-APEX (Accelerated Protein Electron Microscopy) approach.
- Utilizing APEX proximity labeling to capture the ciliary proteome at specific time points.
Main Results:
- Cilia-APEX provides dynamic "snapshots" of the ciliary proteome.
- Enabled detailed analysis of protein localization and interactions within the cilium.
Conclusions:
- Cilia-APEX is a powerful tool for investigating primary cilium function.
- This method advances the study of signaling pathways in development and disease.

Microtubules in Signaling
2.3K
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...

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

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.
