Lab Overview
Amino acids are the building blocks of proteins and other important biological molecules. The sulfur containing amino acid methionine is especially interesting as alterations in methionine metabolism and methionine-related pathways are found in many human diseases, including rare inborn errors of metabolism to common diseases such as cardiovascular disease and cancer. Currently there are three major projects in the lab. Two concern particular methionine metabolic genes, cystathionine beta-synthase (CBS) and methylthioadenosine phosphorylase (MTAP). A third project is related to understanding how alterations in amino acid metabolism contributes to renal cell carcinoma.
