Sppl3 Gene Summary [Mouse]
Predicted to enable aspartic endopeptidase activity, intramembrane cleaving and protein homodimerization activity. Involved in T cell receptor signaling pathway; positive regulation of calcineurin-NFAT signaling cascade; and positive regulation of cytosolic calcium ion concentration. Located in endoplasmic reticulum-Golgi intermediate compartment membrane. Is expressed in central nervous system; gonad; retina; and vibrissa. Orthologous to human SPPL3 (signal peptide peptidase like 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Sppl3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
