SPPL2a Antibody (N-term)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - SPPL2a Antibody (N-term) AP6312a
    The anti-SPPL2a Pab (Cat. #AP6312a) is used in Western blot to detect SPPL2a in Jurkat cell lysate.
  • IHC-P - SPPL2a Antibody (N-term) AP6312a
    Formalin-fixed and paraffin-embedded placenta tissue reacted with SPPL2a Antibody (N-term)(Cat.#AP6312a), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Synonyms IMP3, PSL2
Function Intramembrane-cleaving aspartic protease (I-CLiP) that cleaves type II membrane signal peptides in the hydrophobic plane of the membrane. Functions in FASLG, 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. Also responsible for the intramembrane cleavage of Fas antigen ligand FASLG, which promotes the release of the intracellular FasL domain (FasL ICD). May play a role in the regulation of innate and adaptive immunity.
Cellular Location Late endosome membrane; Multi- pass membrane protein. Lysosome membrane; Multi-pass membrane protein. Cell membrane. Note=Colocalizes with palmitoylated and myristoylated proteins at the plasma membrane
Tissue Location Ubiquitous..

By searching sequence databases for homologs of Dictyostelium discoideum Impas, which shares homology with presenilin, followed by PCR of lymphocyte and hippocampus cDNA libraries, Grigorenko et al. (2002) cloned SPPL2a. This protein, which may act as an intramembrane protease, contains an N-terminal protease-associated (PA) domain, several transmembrane regions, a hydrophilic loop, conservative sequences around the first and second aspartate residues, and an invariant PAL motif near the C terminus.
