In our lab, we use biochemical, cell biological, genetic, and molecular approaches in conjunction with the yeast system to better understand the impact of modifications associated with isoprenylated proteins. Examples of such proteins include the Ras family of oncoproteins, Ras-related proteins, kinases, secreted fungal mating pheromones, Hsp40 chaperones, and many others. Understanding the function of these modifications may lead to novel therapeutic strategies for cancer, Alzheimer's disease, progeria, and other diseases.

Novel Reporters:
Protein isoprenylation is a widespread modification that has been investigated using relatively few reporter proteins. We are developing new reporters to investigate the impact of modifications typically associated with this pathway.

The CaaX Proteases: Rce1p and Ste24p are ER membrane-localized proteases. Rce1p removes the last few amino acids of isoprenylated proteins that are involved in cellular transformation (e.g., Ras and RhoB). Ste24p is required for lamin A production and its dysfunction is linked to premature aging (progeria). Our research investigates the proteolytic mechanisms and substrate profiles of these proteases. This effort is expected to ultimately guide better therapeutic strategies (e.g. cancer treatments) and lead to a better understanding of their relative physiological importance in regulating the function of isoprenylated proteins.

The M16A Proteases: Ste23p and Axl1p are zinc-dependent metalloproteases that are part of the M16A subfamily of metalloproteases. The M16A family includes the insulin-degrading enzyme (IDE) that has a proposed protective function in Alzheimer's disease (AD). Our research on Ste23p and Axl1p is designed is to gain a better understanding of these largely uncharacterized yeast proteases and the M16 metalloprotease family as a whole, thus potentially providing novel insight into new methods for the treatment of AD.


The RAS Initiative: Want to learn more about Ras and therapeutic approaches aimed at interfering with Ras biology? The National Cancer Institute recently launched a national campaign to develop resources and new knowledge about Ras biology.
