Scientists characterize proteome of human cornea

...ational group of researchers has characterized the proteome of the human cornea. In doing so, they have identified 141 distinct proteins, 99 of which had not been previously recognized in mammalian corneas. The details of their findings appear in the August/September issue of Molecular and Cellular Proteomics...

A catalogue of proteins

...w proteins that comes with it. In this study, the proteome researchers looked at liver cells in mice. Using mass spectrometry, and by comparing databases, the scientists were able to detect more than 1400 proteins, localised in ten different cell compartments. Previous analyses had shown that certain protein...

...y and pharmacology. The researchers compared the proteome (the entire complement of proteins expressed at a given time) between the two groups by separating all of the proteins and then using high-throughput mass spectrometry which allowed the accurate identifcation of thousands of proteins simultaneously, ...

Study offers innovative profile of enzyme that aids tumor growth

...filing technologies that survey both the enzymatic proteome and its primary biochemical output, the metabolome," Cravatt said. So, the team drew both on proteomics-the large-scale study of the structure and function of proteins-and metabolomics-the systematic study of cellular processes, specifically thei...
