"Mods – modifications – small alterations can have a big impact on form and function. In the motorsports world, stock vehicles are modified to enhance their performance. Modifications, or mods, to the engine, drive train, intake and exhaust components add up to provide phenomenal performance gains that can be measured as horsepower and torque increases, which yield a competitive advantage, and result in reduced run times. In biology, proteins undergo modifications that alter their function. Some proteins require the modifications in order to perform their function effectively, whether it’s a pro-protein that is cleaved to produce an active enzyme, or a protein that is phosphorylated to facilitate a signaling process. Other proteins, such as histones, undergo modifications that regulate gene expression and alter cellular function. There are several post translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination that impact protein function and activity. As a result, the analysis of proteins and their post-translational modifications are particularly important for the study of normal and disease-associated processes. New antibodies to detect phospho Histidines are now available from EMD Millipore."
