Happy Halloween!!!

This week we look at a very spooky protein, BAT3 which localizes to the nucleoplasm (looks like jack o'lanterns if you squint hard enough) and cytoplasm of the cell as seen in Figure 1 in A-431 cells.

In addition to having a spooky name, this protein, also known as BAG6, was first identified as being involved in programmed cell death (apoptosis). Subsequent studies have revealed that BAT3 plays a role in many important cellular processes including gene regulation, protein synthesis, protein quality control, and protein degradation (Binici J & Koch J. 2014)...Read more


Important link between genomics and proteomics

Several previous reports have concluded that RNA levels cannot be used to predict protein levels. However, in a new study from KTH Royal Institute of Technology, published in the journal Molecular Systems Biology scientists from the Human Protein Atlas show that protein levels can be predicted from RNA levels if a gene-specific RNA-to-protein factor is used.

The human genome consists of DNA, a molecule that contains the instructions needed to build and maintain cells. For the instructions to be carried out, DNA must be read and transcribed into RNA transcripts that can be used to produce protein. The transcriptome is a collection of all the transcripts present in a cell...Read more


Image of the week - the Kinetochore

It's time for another HPA image of the week! This week we would like to tease an annotation that is not yet publicly available, but is coming soon in the December 4 release of the Cell Atlas.

During the cell cycle, each chromosome containing your DNA replicates. During mitosis, each chromosome lines up with its copy in the middle of the cell. At this point, the copies of each chromosome are pulled apart from each other via a structure called the mitotic spindle. In order for this chromosomal separation to happen correctly, the two copies of each chromosome must be attached to the microtubules via the kinetochore ( DeLuca J.G. et al 2002)...Read more


Affinity proteomics for plasma biomarker screening

In a recent study, published in Blood, researchers have used affinity reagents from the Human Protein Atlas project to analyze plasma samples to identify candidate protein markers associated with risk of venous thromboembolism.

Venous thromboembolism is the third most common cardiovascular disease and a leading cause of death and disability worldwide. Complex interactions between genetic, environmental and acquired risk factors underlie disease development. The first step in the process of developing clinically applicable predictive tools is the identification of novel markers that associate with the disease...Read more


Understanding endothelium in health and disease

In a recent publication in Cell Systems researchers have identified endothelial biomarkers that provide potential vascular drug targets and candidates for functional studies to increase understanding of the endothelium in health and disease.

Endothelial cells line the inside of all vessels and have a critical role in the regulation of hemostasis, inflammation, defense against blood borne pathogens, vascular tone, angiogenesis, and the transport of molecules and nutrients to and from the blood stream.

Proteins critical for these specialized functions tend to be predominantly expressed in endothelial cells across vascular beds...Read more
