  • Title: III. Functions of short lifetime structures at large 9: case of nucleic acids.
    Author: Nishigaki K.
    Journal: Brief Funct Genomics; 2018 Jun 20; 18(3):205-210. PubMed ID: 30247522.
    Abstract:
    The short lifetime structures of nucleic acids are not well studied because of the poor recognition of their importance and the methodological difficulty. In case of proteins, which are a type of single-stranded biopolymers, the essential roles of their transient structures are well established. Therefore, the role of transient structures of nucleic acids is, naturally, of great interest. There have been multiple reports on the function-related unstable (transient) structures of single-stranded nucleotides, though not as many as at present. Recent methodological advances are now enabling us to observe structures with ultra-short lifetime (less than a nanosecond). On the other hand, the biological importance of transient structures of ribonucleicacid (RNA) is increasingly recognized because of the findings of novel functional RNAs such as microRNA. Therefore, the time has come to tackle the structure and function dynamic of RNA/deoxyribonucleic acid in relation to their transient, unstable structures. The specific properties of rapidity and diversity are hypothesized to be involved in unexplored phenomena in neuroscience.
