Chromatin Structure Regulates pre-mRNA Processing

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

Master Transcription Regulators

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Transcription Initiation

Transcription Initiation

Initiation is the first step of transcription in eukaryotes. Prokaryotic RNA Polymerase (RNAP) can bind to the template DNA and start transcribing. On the other hand, transcription in eukaryotes requires additional proteins, called transcription factors, to first bind to the promoter region in the DNA template. This binding helps recruit the specific RNAP that can assemble on the DNA and start transcription.
The promoters and enhancers and their accessory proteins allow tight regulation of...

pre-mRNA Processing

pre-mRNA Processing

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl guanosine). This 5’ cap helps the...

Ribosomal RNA Synthesis

Ribosomal RNA Synthesis

Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Summary

Mutations in methyl-CpG-binding protein 2 (MECP2) cause Rett syndrome (RTT). This study identifies a novel MeCP2 complex in the brain, interacting with splicing factor Prpf3, suggesting a role in mRNA processing and RTT.

Background:

Mutations in MECP2 cause Rett syndrome (RTT), a severe neurodevelopmental disorder.
MeCP2 is a multifunctional protein involved in gene regulation, nuclear organization, and potentially mRNA splicing.

Purpose of the Study:

To biochemically identify MeCP2 protein complexes in the mammalian brain.
To investigate the role of MeCP2 in mRNA biogenesis and RTT pathogenesis.

Main Methods:

Biochemical purification of MeCP2 complexes from mammalian brain.
In vitro and in vivo interaction studies between MeCP2 and Prpf3.
Analysis of MeCP2-Prpf3 complex integrity in RTT-associated MECP2 mutations.

Main Results:

MeCP2 exists in at least four distinct biochemical pools in the brain.
A novel MeCP2 complex containing splicing factor Prpf3 was identified.
MeCP2 directly interacts with Prpf3, and RTT-associated MECP2 truncations disrupt this complex.
MeCP2 and Prpf3 associate with mRNAs, supporting a role in mRNA biogenesis.

Conclusions:

MeCP2 plays a role in mRNA biogenesis through interaction with splicing factors.
Disruption of the MeCP2-Prpf3 complex may represent an additional mechanism contributing to RTT pathophysiology.
