33 Facts About LncRNA

What is lncRNA?

Long non-coding RNAs (lncRNAs) are a type of RNA molecule that do not code for proteins. Despite this, they play crucial roles in regulating various biological processes. Let's dive into some fascinating facts about lncRNAs.

1. lncRNAs are typically longer than 200 nucleotides.
2. Unlike mRNAs, lncRNAs do not translate into proteins.
3. They can be found in both the nucleus and cytoplasm of cells.
4. lncRNAs can regulate gene expression at multiple levels, including chromatin modification, transcription, and post-transcriptional processing.
5. Some lncRNAs act as molecular scaffolds, bringing together different proteins to form functional complexes.

Functions of lncRNA

lncRNAs are involved in a wide range of cellular functions. Here are some key roles they play:

6. lncRNAs can influence the structure of chromatin, affecting how genes are expressed.
7. They can act as decoys, binding to proteins or other RNAs to prevent them from interacting with their intended targets.
8. Some lncRNAs serve as guides, directing proteins to specific locations in the genome.
9. lncRNAs can also act as sponges, binding to microRNAs and preventing them from degrading target mRNAs.
10. They are involved in the regulation of cell differentiation and development.
