post-transcriptional modification

vr.tr.post-transcriptional-modification · thing-q417379

Let an agent explain post-transcriptional modification, relay capping, splicing, polyadenylation, editing and tRNA and rRNA processing from molecular biology sources, describe disease links and therapies that target splicing, flag the misfiled protein alias, and distinguish post-transcriptional from transcriptional and post-translational modification and from epigenetic DNA modification.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled

The set of chemical changes made to a primary RNA transcript after transcription to produce mature functional RNA, including in eukaryotic messenger RNA the addition of a 5 prime cap, splicing to remove introns, including alternative splicing that yields multiple proteins from one gene, 3 prime cleavage and polyadenylation, and RNA editing such as adenosine-to-inosine editing, as well as processing and nucleotide modifications of transfer and ribosomal RNA; the registry alias arginylation names the addition of arginine to proteins, a post-translational modification, and appears misfiled. Errors in processing, such as splicing mutations, cause diseases including spinal muscular atrophy.

Why it exists Filled

Let an agent explain post-transcriptional modification, relay capping, splicing, polyadenylation, editing and tRNA and rRNA processing from molecular biology sources, describe disease links and therapies that target splicing, flag the misfiled protein alias, and distinguish post-transcriptional from transcriptional and post-translational modification and from epigenetic DNA modification.

Distinguishing features Filled

  • Acts on RNA
  • Nuclear processing in eukaryotes
  • Alternative splicing diversity
  • Therapeutic target

What robots and AI may and may not do Filled

Must not

  • Confuse post-transcriptional RNA changes with post-translational protein changes.
  • Oversimplify gene expression as one gene making one protein.
  • Present preliminary research on RNA-based therapies as established treatment.
  • File protein modification aliases under RNA processing.

Only with a human decision

  • Using research findings on RNA processing in clinical decisions for a patient.

May

  • Explain RNA capping, splicing, polyadenylation and editing from molecular biology sources.
  • Distinguish RNA processing from protein modification.

Moral aspects Filled

Note: Written from model knowledge without web access; claims are unverified.

Open questions

  • The registry alias arginylation should be moved to post-translational modification
  • Should RNA editing be a separate entry?
  • How should molecular biology references be linked?
