Types of RNA01:23

Types of RNA

61.2K
Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

64.5K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Neural Regulation01:37

Neural Regulation

34.6K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Amyloid Fibrils03:03

Amyloid Fibrils

10.1K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

RNA Splicing01:32

RNA Splicing

53.3K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Summary

RNA-binding proteins (RBPs) regulate gene expression post-transcriptionally, crucial for neuronal function and development. Dysfunctional RBPs are implicated in neurological diseases, highlighting their essential role in brain health.

Area of Science:

  • Molecular Biology
  • Neuroscience
  • Genetics

Background:

  • Gene activity in eukaryotes is complex, involving post-transcriptional regulation of mRNA.
  • The ribonome, encompassing mRNA processing, transport, stability, and translation, is controlled by RNA-binding proteins (RBPs).

Purpose of the Study:

  • To highlight the essential role of RBPs in the nervous system.
  • To underscore the involvement of RBPs in neurogenesis, neurite outgrowth, synapse formation, and plasticity.
  • To establish the link between RBP dysfunction and neurological diseases.

Main Methods:

  • Review of existing literature on RNA-binding proteins and their functions in eukaryotic cells.
  • Analysis of the specific roles of RBPs within the complex architecture of neurons.
  • Examination of the etiological connection between RBP perturbations and neurological disorders.

Main Results:

  • RBPs are critical regulators of the ribonome, influencing gene expression post-transcriptionally.
  • RBPs are indispensable for fundamental neuronal processes including neurogenesis, neurite outgrowth, synapse formation, and plasticity.
  • Alterations in RBP function are central to the pathogenesis of various neurological diseases.

Conclusions:

  • RNA-binding proteins are vital for normal brain function and neuronal development.
  • Dysregulation of RBPs is a significant factor in the etiology of neurological conditions such as fragile X syndrome, frontotemporal lobar degeneration, and amyotrophic lateral sclerosis.
