LncRNAs regulate target proteins in other forms.By Figdraw. (A) LncRNAs promote target protein stability by inhibiting the binding of target proteins to enzymes to avoid target protein degradation. (B) LncRNAs act as brackets to recruit two (or more) proteins together and facilitate recognition between proteins. (C) LncRNAs occupy protein-receptor binding sites located on target proteins (or target protein receptors) and inhibit the target proteins from performing their functions. (D) LncRNAs are capable of encoding peptides.
