RNA-binding proteins in neurological diseases

Area of Science:

• Molecular Biology
• Genetics
• Neuroscience

Background:

• RNA-binding proteins (RBPs) are vital for regulating RNA metabolism, including splicing, transport, and translation.
• Aberrant expression or mutations in RBPs can disrupt RNA processing, impacting gene function.
• RBPs are increasingly implicated in the pathogenesis of various human diseases, notably neurological disorders.

Purpose of the Study:

• To review the functions of key RNA-binding proteins.
• To discuss the roles of selected RBPs in human diseases.
• To highlight the significance of RBPs in both normal biology and disease.

Main Methods:

• Literature review of emerging studies on RBPs.
• Focus on specific RBPs: Nova-1/Nova-2, HuR/HuB/HuC/HuD, TDP-43, Fus, Rbfox1/Rbfox2, QKI, and FMRP.
• Analysis of RBP involvement in RNA processing and disease.

Main Results:

• RBPs regulate diverse RNA metabolic processes.
• Altered RBP activity contributes to disease phenotypes.
• Specific RBPs like TDP-43 and FMRP are strongly associated with neurological diseases.

Conclusions:

• RBPs are critical regulators of gene expression and cellular function.
• Dysfunctional RBPs are implicated in the etiology of numerous diseases.
• Further research into RBPs offers potential therapeutic targets for diseases.
