Protein Structure

UniProt Annotation

Function

Pseudokinase that plays a key role in TNF-induced necroptosis, a programmed cell death process. Activated following phosphorylation by RIPK3, leading to homotrimerization, localization to the plasma membrane and execution of programmed necrosis characterized by calcium influx and plasma membrane damage. Does not have protein kinase activity. {ECO:0000269PubMed:22265413, ECO:0000269PubMed:22265414, ECO:0000269PubMed:22421439, ECO:0000269PubMed:24316671}.

Subcellular Localization

Cytoplasm {ECO:0000269PubMed:24316671}. Cell membrane {ECO:0000269PubMed:24316671}. Note=Localizes to the cytoplasm and translocates to the plasma membrane on necroptosis induction.
