E3 ubiquitin-protein ligase SIAH2 is an enzyme that in humans is encoded by the SIAH2 gene.[4][5]

Function[edit]

This gene encodes a protein that is a member of the seven in absentia homolog (SIAH) family. The protein is an E3 ligase and is involved in ubiquitination and proteasome-mediated degradation of specific proteins. The activity of this ubiquitin ligase has been implicated in regulating cellular response to hypoxia.[5]

Interactions[edit]

SIAH2 has been shown to interact with PEG10,[6] Synaptophysin,[7] PEG3[8] and VAV1.[9]
