Binding to a long noncoding RNA (lncRNA). [PMID:25578728]
Long non-coding RNAs (lncRNAs) are RNA transcripts longer than 200 nucleotides that do not encode proteins. Despite lacking protein-coding potential, lncRNAs play diverse and crucial roles in cellular processes, including gene regulation, chromatin remodeling, and signal transduction. LncRNA binding, a central aspect of their function, involves the interaction of lncRNAs with various molecular partners, including proteins, DNA, and other RNA molecules. These interactions often lead to the modulation of target molecule activity, resulting in a wide range of cellular effects.
One primary function of lncRNA binding is to regulate gene expression. LncRNAs can act as scaffolds, bringing together different proteins and facilitating their interactions. For example, lncRNAs can recruit transcription factors or chromatin modifiers to specific genomic loci, thereby influencing gene transcription. They can also act as decoys, sequestering regulatory proteins away from their target genes, leading to gene silencing.
LncRNAs can also bind to DNA, affecting chromatin structure and accessibility. Some lncRNAs can interact with chromatin-modifying enzymes, directing their activity to specific genomic regions and influencing gene expression. Others can bind to DNA and block the binding of transcription factors, preventing gene activation.
In addition to protein and DNA interactions, lncRNAs can bind to other RNA molecules, including messenger RNAs (mRNAs), microRNAs (miRNAs), and other lncRNAs. LncRNA-mRNA interactions can regulate mRNA stability, translation, and localization, influencing protein production. LncRNA-miRNA interactions can modulate miRNA activity, influencing gene expression.
LncRNA binding can also play a role in signal transduction. LncRNAs can act as sensors of cellular signals, responding to changes in the cellular environment and modulating downstream signaling pathways. They can also act as messengers, relaying information from one cellular compartment to another.
Overall, lncRNA binding is a complex and dynamic process with a wide range of molecular functions. It is a key aspect of lncRNA-mediated regulation, influencing a multitude of cellular processes. Understanding the molecular mechanisms underlying lncRNA binding is essential for unraveling the roles of these enigmatic transcripts in health and disease.'
