The 2003 Human Genome Project revealed the draft sequence of the human genome. However, many new human genes have been found even now and the information of the human genome is still being repeatedly added and modified.
Meanwhile, it varies greatly which genes are expressed and how much they are expressed between human cell types or individuals, as well as between humans, mice, and primates (Fig. 1). In fact, the analysis of the different gene expression in leucocyte and sperm cells of human leads the finding of many non-canonical ORFs.
It is expected that the analysis of gene expression using various cell types will be a powerful tool for complementing the human genome. However, the attempts to reveal the overall picture of diverse gene expression in various cell types are still advanced.
Among the analysis of gene expression, I am using ribosome profiling to comprehensively investigate RNA regions being translated by ribosomes (Fig. 2). I am analyzing various cell types by ribosome profiling in order to discover new ORFs on the human genome.
