Critical function of Siah2 in tumorigenesis

Department of Probiotics Immunology, Institute for Genetic Medicine, Hokkaido University, North 15 West 7, Kita-ku, Sapporo City, Hokkaido, Japan

The seven in absentia homolog (Siah) family proteins are components of E3 RING zinc finger ubiquitin ligase complexes that catalyze the ubiquitination of proteins. Siah proteins target their substrates for proteasomal degradation. Evidence is growing that Siah proteins are implicated in the progression of various cancer cells and play a critical role in angiogenesis and tumorigenesis, particularly through Ras, p53, estrogen, and hypoxia inducible factor (HIF)-mediated signaling pathways in response to DNA damage or hypoxia.
