Scientific Data Images for Human Leucyl-cystinyl Aminopeptidase/LNPEP Antibody

Detection of Human Leucyl-cystinyl Aminopeptidase/LNPEP antibody by Western Blot.

Detection of Human Leucyl-cystinyl Aminopeptidase/LNPEP by Western Blot.

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human Leucyl-cystinyl Aminopeptidase/LNPEP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6386) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Leucyl-cystinyl Aminopeptidase/LNPEP at approximately 170 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Leucyl-cystinyl Aminopeptidase/LNPEP

LNPEP (also known as P-LAP, CAP, IRAP, and Oxytocinase) is a 165-175 kDa member of the oxytocinase subfamily, M1 family of zinc metallopeptidases. It is widely expressed after cell stimulation and is found on endothelial cells, trophoblasts, skeletal muscle cells, neurons, adipocytes, and renal distal tubule epithelium. LNPEP cleaves vasopressin and oxytocin and serves as a receptor for AngIV. Human LNPEP is a 1025 amino acid (aa) type II transmembrane glycoprotein (SwissProt #:Q9UIQ6). It contains a 110 aa cytoplasmic region (aa 1-110) plus an 894 aa extracellular domain (aa 132-1025) that contains a peptidase M1 region (aa 168‑552). There are multiple potential splice variants. There are two alternative start sites at Met15 and Met20, and the cytoplasmic tail undergoes phosphorylation at Tyr70 and Ser80. LNPEP is reportedly forms homodimers. Proteolytic cleavage between Phe154Ala155 generates a 150-155 kDa soluble form. Over aa 133-552, human LNPEP shares 89% aa sequence identity with mouse LNPEP.
