Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human gamma-Glutamylcyclotransferase/CRF21 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5086) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for gamma-Glutamylcyclotransferase/CRF21 at approximately 21 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: gamma-Glutamylcyclotransferase/CRF21

Gamma-glutamylcyclotransferase (GGCT; also Cytochrome c-releasing factor 21, CRF21, C7orf24 or LOC79017) is a 21 kDa AIG2-like family member. It is a cytosolic protein that induces the release of Cytochrome c from mitochondria, possibly initiating apoptosis. Human CRF21 is 188 amino acids (aa) in length and is a complex of beta-sheets and alpha-helices that create two terminal domains. It has been proposed that CRF21 forms homodimers. There are at least two possible splice variants of human CRF21, one showing a 70 aa substitution, while the second variant shows an 18 aa substitution for aa 97‑188. Full-length human CRF21 is 82% aa identical to mouse CRF21.
