Rhomboid-family intramembrane proteases regulate important biological processes and have been associated with malaria, cancer, and Parkinson's disease. However, due to the lack of potent, selective, and pharmacologically compliant inhibitors, the wide therapeutic potential of rhomboids is currently untapped. Here, we

The expression of thrombomodulin (TM), a membrane glycoprotein, is upregulated in neoepidermis during cutaneous wound healing. Rhomboid-like-2 (RHBDL2), an intramembrane serine protease, specifically cleaves TM at the transmembrane domain and causes the release of soluble TM (sTM). However, the physiological
