1Center for Cell Structure and Function, Shandong Provincial Key Laboratory of Animal Resistance Biology, College of Life Sciences, Shandong Normal University, Jinan, 250014, China.
Summary
Post-translational modifications (PTMs) are crucial for ciliary function and cellular health. Understanding these PTMs in cilia offers new therapeutic targets for treating human diseases known as ciliopathies.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Cilia are vital microtubule-based organelles in vertebrate cells, essential for development and tissue maintenance.
- Defects in ciliary proteins cause human diseases called ciliopathies.
- Post-translational modifications (PTMs) significantly impact ciliary protein function.
Purpose of the Study:
- To review current knowledge on PTMs in ciliary proteins.
- To highlight the role of PTMs in ciliary formation, homeostasis, and signaling.
- To discuss the link between aberrant PTMs and ciliopathies.
Main Methods:
- Literature review of PTMs in ciliary proteins.
- Analysis of enzymes responsible for PTMs.
- Examination of PTM roles in ciliary structure and function.
Main Results:
- Specific PTMs like α-tubulin acetylation and pericentriolar material 1 ubiquitination are critical for ciliary assembly, maintenance, and disassembly.
- PTMs are essential regulators of ciliary structure, function, and signaling pathways.
- Dysregulation of PTMs is a key factor in ciliogenesis defects and ciliopathies.
Conclusions:
- PTMs are fundamental to ciliary biology and are implicated in various human diseases.
- Targeting PTMs or related enzymes presents a promising therapeutic strategy for ciliopathies.

01:22Microtubules in Signaling
1.8K
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...

02:04Covalently Linked Protein Regulators
7.5K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

4.0K
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...

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

2.5K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the...

01:26Protein Modifications in the RER
5.7K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...
