The CRISPR (Clustered, Regularly Interspaced, Short Palindromic Repeats)-Cas (CRISPR-associated) (CRISPR-Cas) system has become trendy as it is suitable for numerous applications such as gene knockouts, genome-engineering, to name but a few. In a recent Technical Bulletin, Ed Davis describes the mechanism of CRISPR-Cas for genome editing and how the recent experimental improvements improve CRISPR-Cas9 specificity while reducing off-target effects.

Proteome is referenced as the result of expression of the whole genome. With the recent developments of genomics, one could consider that this analysis is enough to decipher any biological mechanism…
But depending on your sample, some regulations occur, that are not directly linked to the genes: isoform splicing, post-translational modifications (such as phosphorylation, acetylation & glycosylation), secretion…

Genomics, although powerful, does not allow the analysis of such protein-specific modifications. To overcome these limits, proteomics emerges, with specific subsets having specific requirements. Here, I’d like to put the Secretome and Kinome in the highlight!
