Human breast cancer can be classified by gene expression into four or five subtypes, and the treatment plans are decided based on the subtypes. From this standpoint, it is important to elucidate molecular mechanisms of the determination of breast cancer characteristics, which could lead to the development of novel therapy for breast cancers. In this research proposal, we focused on a ubiquitin E3 scaffold protein, cullin-3 (CUL3), and found that CUL3 is essential for Rac1 activation and cell proliferation specifically in HER2-positive breast cancer cells.
