Only 2% of the human genome codes for a protein [1], and yet 75% is transcribed [2]. These non-coding RNAs (ncRNAs) show a mind-boggling heterogeneity of sizes, shapes, origins and functions. Many ncRNAs are essential, either directing or fine-tuning cellular, and a few types are so poorly understood that they may even be junk.
I have counted at least 22 types of ncRNAs. I have compiled them in a list, with the celebrities of the RNA world (ribosomal RNAs, transfer RNAs, microRNAs..) and the obscure, more exotic underdogs (microRNA-offset RNAs, transcribed-ultraconserved regions, promoter-associated RNAs…)
We are going to discuss them all, 3 types of ncRNA on my blog.and on my LinkedIn profile
The travel start this Sunday, fellow travellers!
The journey so far:
- Episode 1/7: ribosomal RNA (rRNA), transfer RNA (tRNA) and transfer-derived small RNA (tsRNA),
- Episode 2/7: small nucleolar RNA (snoRNA), sno-derived RNAs ( sdRNA ), small Cajal-specific RNA (scaRNA).
- Episode 3/7: microRNA (miRNA), endogenous-small interfering RNA (endo-siRNA), PIWI-interacting RNA (piRNA),
- Episode 4/7: microRNA-offset RNA (moRNA), circular RNA (circRNA), small nuclear RNA (snRA).
