In the latest version of the Human Protein Atlas, released in December 2016, the tissue atlas data is complemented with RNA-data from The Functional Annotation of Mammalian Genomes 5 (FANTOM5) project in RIKEN, Japan. The FANTOM data greatly overlaps with the Human Protein Atlas data, strengthening the results from both the projects.

The human genome consists of DNA which is transcribed into functional protein-coding transcripts (mRNA) and in turn is translated into proteins, the functional building-blocks of the cell. The entirety of mRNA molecules in a cell or tissue is called the "transcriptome"...Read more

A large number of proteins are needed in all cells throughout the human body. These proteins are sometimes called housekeeping proteins, suggesting that their expression is crucial for the maintenance of basic functionality of all normally functioning cells.

A transcriptomics analysis shows that about 9,000 genes are expressed in all tissues and are therefore expected to fulfill these tasks, such as gene expression, metabolism, and cell structure.

As for gene expression, it is easily understood that every cell must have proteins that are involved in the genetic machinery of translating DNA to functional proteins, like RNA polymerases and ribosomal proteins...Read more

Today, a new version, number 15, of The Human Protein Atlas is launched that includes extensive transcriptomics data and a new display view to allow comparisons of human tissue profiles on both the RNA and protein level. In this new version it is possible to do comparisons of primary data from several sources, including external efforts such as the GTEx dataset generated from the Broad Institute in Boston, US.

The GTEx dataset includes more than 1600 postmortem samples from mostly overlapping, but in some cases unique, tissues compared to the Human Protein Atlas consortium...Read more
