The multifaceted effects of YTHDC1-mediated nuclear m⁶A recognition

Area of Science:

• Molecular Biology
• Epigenetics
• RNA Biology

Background:

• N6-methyladenosine (m⁶A) is a prevalent mRNA modification regulating gene expression and protein translation.
• m⁶A readers interpret these modifications, with most located in the cytoplasm, except for the nuclear YTHDC1 protein.

Purpose of the Study:

• To summarize the current understanding of YTHDC1 function in cellular gene regulation.
• To highlight YTHDC1's diverse roles beyond mRNA processing, including its interaction with non-coding and regulatory RNAs.
• To propose a unifying mechanism for YTHDC1's nuclear functions.

Main Methods:

• Literature review of recent studies on YTHDC1.
• Analysis of YTHDC1's known interactions with RNA species.
• Investigation of YTHDC1's role in transcriptional regulation and nuclear processes.

Main Results:

• YTHDC1's functions extend to alternative splicing, mRNA export, and interaction with chromatin-associated RNAs.
• Recent findings link YTHDC1 to the regulation of transcription and gene expression.
• Evidence suggests YTHDC1 forms nuclear condensates, facilitating its diverse nuclear roles.

Conclusions:

• YTHDC1 is a versatile nuclear m⁶A reader with multifaceted roles in gene expression regulation.
• The formation of YTHDC1 nuclear condensates represents a key mechanism underlying its diverse functions.
• Further research into YTHDC1 condensates will elucidate its precise roles in nuclear processes.
