The entire set of 518 protein kinases in the human genome makes up one of the largest of all human gene families. These enzymes catalyze the phosphorylation of proteins, specifically serine/threonine and tyrosine residues – an important reaction that regulates key cellular functions like cell division, metabolism, and apoptosis in normal and disease states. This makes kinases key therapeutic targets in several diseases such as cancer, neurodegeneration, behavioral disorders, diabetes, and cardiovascular diseases. Interestingly, both the labs that I’ve been in so far are focussed on kinases involved in pancreatic/prostrate cancer and GPCR signaling in the light of alcohol/drug addiction. Leaving this nice phylogenetic tree here as a reminder and reflection of kinome research!
