Scientific Data

Western Blot Detection of Human and Mouse PGPEP-1 antibody by Western Blot. View Larger

Detection of Human and Mouse PGPEP‑1 by Western Blot. Western blot shows lysates of LNCaP human prostate cancer cell line, JAR human choriocarcinoma cell line, NTera-2 human testicular embryonic carcinoma cell line, Neuro-2A mouse neuroblastoma cell line, and human brain (cortex) tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human PGPEP-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6278) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PGPEP-1 at approximately 23 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: PGPEP-1

Pyroglutamyl peptidase-1 (PGPEP-1) is an omega peptidase which removes pyroglutamyl residues from the amino termini of peptides and proteins (1). It is a cytosolic cysteine peptidase that is expressed in most cell types (2). The enzyme requires a thiol‑reducing agent for activity (3). PGPEP-1 is potentially involved in the inactivation of biologically active peptides that possess an amino terminal pyroglutamyl group (3). Examples of such peptides include neurotensin, luteinizing hormone releasing hormone, and thyrotropin-releasing hormone. Human and mouse PGPEP-1 share 95% aa sequence identity.
