| Research Abstract |
We made cDNA libraries using oligocapping method of various normal tissues, tumors and cell lines. From those, we isolated about 1.65 million cDNA clones and determined their 5' EST sequence. Using about 1,5 million 5'EST data, we did clustering and mapping to human genome sequence. As the result, we could determine the transcriptional start sites for 19,000 known genes. We picked up up-stream 1000bp region for the putative promoters of those genes.
We made database DBTSS using above data and made public through web sites.
We also cloned promoter regions of about 500 genes and determined their activity in cultured cells. Similarly, we cloned random genomic fragments which do not include any promoter regions and assayed their activity. About 10% of the clones showed weak promoter activity. We currently think this observation may correspond to the abundance of the non-coding RNA found among the transcripts.
We also performed proteome analysis of the small sized protein. The result showed a possibility that small ORF present in 5'UTR may actually directs the synthesis of small proteins. We determined the subcellular localization of 3000 proteins whose function is not yet determined.
