| Research Abstract |
ABCA1 expression is regulated negatively by a transcriptional factor AP2 and its protein level is modulated by calpain-mediated proteolytic degradation. In this research project, I demonstrated that regulation of the ABCA1 gene by AP2 is mediated by its phosphorylation by PKD, which is similar to negative regulation of the adiponectin gene. I also showed that calmodulin binds ABCA1 and suppress its calpain-mediated degradation. A calmodulin inhibitor W7 enhanced calmodulin binding to ABCA1 to increase HDL biogenesis.
