Sppl2a - signal peptide peptidase like 2A

Predicted to enable aspartic endopeptidase activity, intramembrane cleaving and protein homodimerization activity. Predicted to be involved in membrane protein ectodomain proteolysis; membrane protein intracellular domain proteolysis; and regulation of immune response. Predicted to act upstream of or within proteolysis. Located in late endosome membrane and lysosomal membrane. Is expressed in genitourinary system; skeleton; and thymus primordium. Human ortholog(s) of this gene implicated in primary immunodeficiency disease. Orthologous to human SPPL2A (signal peptide peptidase like 2A). [provided by Alliance of Genome Resources, Apr 2022]
