Summary
Researchers identified a direct interaction between yeast proteins Pcf11 and Ydh1, crucial for messenger RNA (mRNA) processing. This finding illuminates how these proteins assemble complexes for co-transcriptional processing, generating mature mRNA.
Area of Science:
- Molecular Biology
- Biochemistry
- Genetics
Background:
- Pre-messenger RNA (mRNA) processing in eukaryotes involves capping, splicing, cleavage, and polyadenylation.
- Proteins regulating human mRNA processing share homology with yeast proteins, including Pcf11 and Ydh1, vital for nascent transcription processing.
Purpose of the Study:
- To investigate the interaction between yeast Pcf11 and Ydh1 proteins.
- To elucidate the role of specific protein domains in mRNA processing and complex assembly.
Main Methods:
- In silico analysis to predict protein interactions.
- Molecular docking and molecular dynamics (MD) simulations to study protein-protein complex structure, dynamics, and binding affinity.
Main Results:
- Evidence of direct interaction between Pcf11 residues 116-204 (Pcf11^116-204) and Ydh1 N-terminal residues 1-246 (Ydh1^1-246).
- Detailed insights into the binding interface and affinity of the Pcf11-Ydh1 protein complex.
Conclusions:
- The Pcf11^116-204 domain's function in mRNA processing can now be further investigated.
- Findings facilitate understanding the roles of Ydh1 and Pcf11 in assembling the cleavage and polyadenylation complex for co-transcriptional mRNA maturation.

9.2K
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 (7-methyl guanosine). This 5' cap helps...

02:41Chromatin Structure Regulates pre-mRNA Processing
6.9K
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.

02:27Nonsense-mediated mRNA Decay
10.5K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
