Biomolecular Concepts
|November 6, 2014
Summary
Transthyretin (TTR) is vital for brain health beyond its transport functions. This review highlights TTR's diverse roles in the nervous system and its implications in various neuropathologies.
Area of Science:
- Neuroscience
- Biochemistry
- Genetics
Background:
- Transthyretin (TTR) is a conserved homotetrameric protein synthesized primarily in the liver and choroid plexus.
- While known for transporting thyroxine and retinol-binding protein, TTR has emerging roles in the nervous system.
Purpose of the Study:
- To review the multifaceted functions of TTR within the nervous system.
- To emphasize TTR's significance beyond its established transport functions.
Main Methods:
- Literature review of studies on Transthyretin (TTR) and its neurological functions.
- Analysis of TTR's involvement in various physiological and pathological processes in the brain.
Main Results:
- TTR plays crucial roles in behavior, cognition, neurogenesis, and nerve regeneration.
- TTR aggregation is linked to amyloidosis, including familial amyloidotic polyneuropathy and cardiomyopathy.
- Altered TTR levels are observed in neuropathologies, with documented neuroprotective roles in ischemia and Alzheimer's disease.
Conclusions:
- Transthyretin (TTR) exhibits diverse and critical functions within the nervous system.
- Understanding TTR's broader roles is essential for developing therapeutic strategies for neurological disorders.

01:32Export of Misfolded Proteins out of the ER
4.2K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

01:22Protein Transport to the Thylakoids
2.1K
Thylakoids are membrane-bound sac-like structures within the chloroplast that serve as sites for photosynthesis. Thylakoid lumen contains many electron transport proteins and is enclosed by a thylakoid membrane rich in the light-harvesting complex. Proteins targeted to the thylakoids are transported as precursors and are sorted by the general TOC/TIC import pathway. Once the precursor reaches the stroma, stromal processing peptidases remove their transit signal and expose thylakoid signal...

01:27Post-translational Translocation of Proteins to the RER
5.6K
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.

01:29Insertion of Multi-pass Transmembrane Proteins in the RER
13.4K
The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
