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
Welcome back to HPA image of the week! This week we highlight another organelle brought to us by Mikaela Wiking aka HPA_Illuminator, the intermediate filaments!
Intermediate filaments are one of the three cytoskeletons of the cell, together with actin filaments and microtubules.
The expression of intermediate filaments can be extremely dependent on cell type, for example the intermediate filament protein group keratins, discussed in a previous IOTW, are key components in hair, nails and skin...Read more
In January 2015, the Tissue-based map of the human proteome by UhlÚn et al was published. According to Google Scholar, the paper already has more than 400 citations. In a recent editorial by Cecilia Lindskog, the potential utility of the Human Protein Atlas and the Tissue-based map is reviewed.
Cecilia Lindskog is site director of the Tissue Atlas, and you can read more about her and the Tissue Atlas in this blog post from May this year...Read more
Welcome back to Image of The Week! We will be periodically highlighting an organelle in the coming image of the week posts, written by members of the Subcellular Human Protein Atlas project. This week we kick things off with a post by HPA_Illuminator, and what better way to start than with the mitochondria, the (true) powerhouse of the cell!!!
Mitochondria are found in almost all human cells, in varying numbers. They are known as the powerhouse of the cell as they are responsible for producing the majority of the energy in your body (in the form of ATP, adenosine triphosphate)...Read more
In a very recent study, published in Respiratory Research, researchers from the Human Protein Atlas and Karolinska Institutet performed protein profiling of broncho-alveolar lavage (BAL)-fluid and serum using an antibody suspension bead array technology with the aim to find proteins associated to sarcoidosis.
Sarcoidosis is a granulomatous systemic inflammatory disease in which more than 90 % of all patients develop pulmonary manifestations. Several gene associations have previously been described, but established and clinically useful biomarkers are still absent...Read more
