Cheng laboratory: Molecular enzymology of protein kinases and phosphatases involved in human diseases


Research Overview

Protein phosphorylation and dephosphorylation are the most prevalent post-translational modifications regulating the structures and functions of cellular proteins in a wide spectrum of cellular processes, ranging from metabolism to cell fate control.

Even though protein kinase genes constitutive only 2% of the genomes in most eukaryotes, more than 30% of total cellular proteins are phosphorylated. Furthermore, aberrant regulation of protein kinases and phosphatases contributes to pathogenesis and progression of many diseases.

In light of the significant role played by protein kinases phosphatases in cell regulation and disease pathogenesis, research in my group focuses on the biochemical basis of their regulation and function.

Specifically, we focus on the protein kinases and phosphatases involved in cancer formation and progression, and acute and chronic neurological diseases associated with neuronal cell death.
