Cellulose Synthase-Like G proteins (CslG) play a crucial role in the biosynthesis of triterpenoids. In previous research, we discovered that a CslG protein called SOAP5 has unexpected glucuronosyltransferase activity on triterpenoids from spinach. Based on these findings, our lab will continue to investigate the mechanisms behind these functions of CslG proteins and explore their potential for producing diverse triterpenoids. We aim to understand how CslG proteins are redirected to the endoplasmic reticulum, which structural features enable their activity, and what other unknown functions they may have.
