Has E3 ubiquitin protein ligase activity. Regulates the levels of CASP8 and CASP10 by targeting them for proteasomal degradation. Has anti-apoptotic activity. May bind phosphatidylinositol phosphates.
Subunit:
Binds CASP8 and CASP10.
Subcellular Location:
Cytoplasm. Membrane; Peripheral membrane protein.
Tissue Specificity:
Ubiquitous. Detected in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocytes.
Post-translational modifications:
Rapidly degraded after stimulation with TNFSF10, probably by caspases.
Auto-ubiquitinated (in vitro).
Palmitoylated.
Similarity:
Contains 1 FYVE-type zinc finger.
Contains 1 RING-type zinc finger.
Contains 2 SAP domains.
