Predicted to enable aspartic endopeptidase activity, intramembrane cleaving and protein homodimerization activity. Predicted to be involved in membrane protein proteolysis. Predicted to act upstream of or within proteolysis. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in Golgi-associated vesicle membrane and lysosomal membrane. Predicted to be integral component of cytoplasmic side of endoplasmic reticulum membrane and integral component of lumenal side of endoplasmic reticulum membrane. Orthologous to human SPPL2C (signal peptide peptidase like 2C). [provided by Alliance of Genome Resources, Apr 2022]
