Summary
The Translin/Trax complex is crucial for stabilizing Trax protein and is implicated in dendritic RNA trafficking, a key process in synaptic plasticity. Its dysfunction in mice leads to behavioral and synaptic abnormalities.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Translin and Trax form an evolutionarily conserved RNA binding complex.
- Stable Trax protein expression depends on its association with Translin.
Purpose of the Study:
- To investigate the role of the Translin/Trax complex in RNA trafficking and synaptic plasticity.
- To understand the consequences of Translin deletion on Trax protein levels and neuronal function.
Main Methods:
- Analysis of Translin knockout (KO) mice.
- Biochemical and localization studies.
- RNA trafficking assays.
Main Results:
- Translin deletion causes significant loss of Trax protein in various organisms.
- Translin KO mice exhibit behavioral abnormalities and altered synaptic protein transcript levels.
- Evidence supports the Translin/Trax complex's role in dendritic RNA trafficking.
Conclusions:
- The Translin/Trax complex is essential for Trax stability and likely mediates dendritic RNA trafficking.
- This complex is functionally analogous to other known RNA regulators like Staufen and CPEB.
- Further research is needed to fully elucidate its RNA targets and regulatory mechanisms in neurons.

01:28Protein Translocation Machinery on the ER Membrane
The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the translocon complex.

01:29Translational Regulation
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...
01:20Cotranslational Protein Translocation
Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:19RNA Structure
The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
