Summary
Phosphorylated CTD-interacting factor 1 (PCIF1) methylates mRNA, impacting gene expression and disease. New bisubstrate analogs and structural insights offer a starting point for developing PCIF1 inhibitors.
Area of Science:
- Biochemistry
- Molecular Biology
- Structural Biology
Background:
- Phosphorylated CTD-interacting factor 1 (PCIF1) catalyzes the m6Am modification on nascent mRNA.
- This m6Am modification influences mRNA stability, transcription, and translation.
- PCIF1's role in diseases highlights its potential as a therapeutic target.
Purpose of the Study:
- To synthesize bisubstrate analogs of PCIF1 to aid in inhibitor design.
- To generate a structural model of PCIF1 with an RNA substrate.
- To explore the binding interactions of synthesized analogs with PCIF1.
Main Methods:
- Bisubstrate strategy employed for synthesizing PCIF1 analogs.
- Incorporation of S-adenosyl-L-methionine (SAM) analog and Am-modified RNA substrate.
- AlphaFold 3 used for structural modeling; docking studies performed.
Main Results:
- Synthesized bisubstrate analogs with structural diversity.
- Generated a complete PCIF1-RNA complex structure using AlphaFold 3.
- Docking studies confirmed SAM analog in cofactor site and RNA substrate in RNA pocket.
Conclusions:
- The synthesized bisubstrate analogs are valuable tools for PCIF1 research.
- Structural insights provide a foundation for designing potent PCIF1 inhibitors.
- Further development could lead to therapeutic strategies targeting PCIF1-related diseases.

01:53RNA Stability
36.3K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

01:56Riboswitches
10.1K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...

02:23RNA Editing
10.2K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

4.3K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

01:23Regulation of Expression at Multiple Steps
1.5K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
