Description

General description

Signal peptide peptidase-like 2B (SPPL2B, IMP4, PSL1), a homologue of signal peptidase, is a GxGD aspartyl protease that catalyzes regulated intra-membrane proteolysis of type II membrane-anchored signaling factors. SPPL2b catabolizes signaling substrates such as TNFα and Bri2.

Specificity

Anti-SPPL2B polyclonal antibody reacts with human, mouse, rat, chicken, and bovine signal peptide peptidase-like 2B proteins.

Immunogen

Synthetic peptide directed towards the N terminal region of human SPPL2B

Application

Anti-SPPL2B polyclonal antibody is used to tag signal peptide peptidase-like 2B for detection and quantitation by Western blotting and in plasma by immunohistochemical (IHC) techniques. It is used as a probe to determine the roles of signal peptide peptidase-like 2B as a cell signal regulator by mediating the intra-membrane proteolysis of membrane-anchored signaling factors.

Biochem/physiol Actions

SPPL2B is a member of the GXGD family of aspartic proteases. The GXGD proteases are transmembrane proteins with two conserved catalytic motifs localized within the membrane-spanning regions. This enzyme localizes to endosomes, lysosomes, and the plasma membrane. It cleaves the transmembrane domain of tumor necrosis factor alpha to release the intracellular domain, which triggers cytokine expression in the innate and adaptive immunity pathways.
