To study the pathogenesis and its underlying mechanisms of an abnormally large Pol II pool size caused by a defective novel ARMC5-containing POLR2A-specific ubiquitin ligase

FY 2021-22

Summary
We recently found that a molecule called ARMC5 is part of an enzyme called ubiquitin ligase (E3). Its target is a molecule called POLR2A, which is involved in messenger RNA synthesis. This ligase will mark POLR2A for destruction. In mice and humans with ARMC5 mutations, POLR2A is accumulated. This is unhealthy, leading to many types of diseases in newborns and old individuals, such as spinal column deformation and enlarged adrenal glands. In this project, we will try to understand how the accumulation of POLR2A due to ARMC5 mutation causes diseases. Our study will enhance our knowledge regarding how this new E3 works and how its abnormality causes human diseases.
