Function | Intramembrane-cleaving aspartic protease (I-CLiP) that cleaves type II membrane signal peptides in the hydrophobic plane of the membrane. Functions in ITM2B and TNF processing. Catalyzes the intramembrane cleavage of the anchored fragment of shed TNF- alpha (TNF), which promotes the release of the intracellular domain (ICD) for signaling to the nucleus. May play a role in the regulation of innate and adaptive immunity. {ECO:0000269|PubMed:16829951, ECO:0000269|PubMed:16829952, ECO:0000269|PubMed:17965014, ECO:0000269|PubMed:19114711, ECO:0000269|PubMed:22194595}. |
Subcellular Location | Golgi apparatus membrane {ECO:0000269|PubMed:15998642, ECO:0000269|PubMed:17965014}; Multi- pass membrane protein {ECO:0000269|PubMed:15998642, ECO:0000269|PubMed:17965014}. Note=targeted through the entire secretory pathway to endosomes/lysosomes. |
Tissue Specificity | Expressed predominantly in adrenal cortex and mammary gland. {ECO:0000269|PubMed:15385547}. |
