Scientific Data

Detection of Human Girdin by Western Blot. Western blot shows lysates of H69AR human small cell lung cancer cell line, MRC-5 human embryonic lung fibroblast cell line, and A431 human epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Human Girdin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5345) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for Girdin at approximately 200 to 220 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Detection of Human Girdin by Simple WesternTM. Simple Western lane view shows lysates of A431 human epithelial carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for Girdin at approximately 206 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human Girdin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5345) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 66-440kDa separation system.

Background: Girdin
Girdin (GIRDers of actIN filaments; also APE and GIV) is a member of the CCDC88 family of molecules. It is a cytosolic protein, ubiquitously expressed, and plays a key role in the motility of breast cancer cells. Human Girdin is 1871 amino acids (aa) in length. It contains two coiled-coil regions that mediate homodimerization (aa 196-425 and 458-1358), and one phosphoinositide-binding domain (aa 1390-1408). Normally, Girdin is membrane-associated via an interaction with phosphoinositides. Upon phosphorylation at Ser1417 by Akt, it relocates to lamellipodia where it crosslinks actin filaments. Multiple isoforms of Girdin have been detected.
