Summary
Post-translational modifications (PTMs) regulate actin filament formation, stability, and cellular functions. These actin PTMs may also play a role in disease development.
Area of Science:
- Biochemistry
- Cell Biology
Background:
- Actin is a fundamental eukaryotic protein essential for cellular structure and function.
- Actin's roles include muscle contraction, cell integrity, motility, and transcriptional regulation.
- Actin function is modulated by actin-binding proteins (ABPs) and post-translational modifications (PTMs).
Purpose of the Study:
- To elucidate the role of actin post-translational modifications (PTMs) in filament formation and stability.
- To explore potential additional regulatory functions of actin PTMs.
- To investigate the contribution of actin PTMs to disease development.
Main Methods:
- Review of existing literature on actin post-translational modifications.
- Analysis of biochemical pathways involving actin PTMs.
- Correlation of actin PTMs with cellular functions and disease states.
Main Results:
- Actin PTMs, including acetylation, arginylation, and oxidation, influence actin filament assembly and stability.
- PTMs can confer additional regulatory roles beyond basic filament dynamics.
- Aberrant actin PTMs are potentially linked to the pathogenesis of various diseases.
Conclusions:
- Actin PTMs are critical regulators of actin dynamics and cellular processes.
- Understanding actin PTMs offers insights into fundamental cell biology.
- Targeting actin PTMs may present novel therapeutic strategies for diseases involving actin dysfunction.

01:27Post-translational Translocation of Proteins to the RER
7.7K
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...

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.

02:32Histone Modification
16.1K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

02:33Initiation of Translation
39.0K
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

01:44Termination of Translation
27.7K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

01:18Actin Treadmilling
9.7K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...
