| Outline of Final Research Achievements |
We have demonstrated that the promoter-associated noncoding RNA-D (pncRNA-D) transcribed from a promoter region of the cyclin D1 gene represses its expression through binding of pncRNA-D to RNA-binding protein TLS (Nature 454: 126-130, 2008). TLS is found to target the 5’ end (32-62) of pncRNA-D. At the 3’ end (44-62) of pncRNA-D forms a stem-loop structure, while TLS firmly binds to the straight chain of the 5’ end (32-44) of pncRNA. Moreover, high-osmotic treatment of HeLa cells reduced methylation of the N6-adenosine (m6A) at pncRNA-D, but induced its binding to TLS. Recently, we have been analyzing effect of methylation of TLS on its binding to pncRNA-D. Methylation of long ncRNAs (lncRNAs) might regulate their physiological function presenting another exciting issue of the lncRNA biology.
