HIF-1 is a master regulator of oxygen homeostasis via transcription activation. Thus, FIH-1 is an inhibitor of transcriptional activation . Relevance The interaction of FIH-1 with notch 1 suggests that it may play a critical role in controlling the survival of vascular endothelial cells and thus may be used in antiangiogenic strategies in controlling cancer and rheumatoid arthritis. FIH-1 acts as a tumor suppressor in human colorectal cancer. Structural highlights Human FIH-1 dimer complex with HIF-1 C-terminal transactivation domain (PDB code 1h2m). The 3D structure of the complex between FIH-1 and the C-terminal transactivation domain of HIF-1 shows 2 interaction sites between the two proteins: The buried hydroxylation site which includes the Asn which undergoes hydroxylation. The surface interaction site.
