Function

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.[6]

Interactions

SIAH2 has been shown to interact with PEG10,[7] Synaptophysin,[8] PEG3[9] and VAV1.[10]
