Scientific Data

Western Blot Detection of Human FoxF2 antibody by Western Blot. View Larger

Detection of Human FoxF2 by Western Blot. Western blot shows lysates of human liver tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human FoxF2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6988) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for FoxF2 at approximately 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: FoxF2

FoxF2 (Forkhead box protein F2; also FREAC-2 and FKHL6) is a 42-46 kDa member of the winged helix transcription factor gene family. It is a transcriptional activator that is expressed in embryonic mesenchyme, inducing the synthesis if BMP4 and ECM. In the adult, it is expressed in placenta and lung, specifically in type II pneumocytes plus bronchiolar epithelium, inducing the synthesis of C10 and surfactant proteins B and C. Human FoxF2 is 444 amino acids (aa) in length. It contains one poly-Ala repeat (aa 33-41), a poly-Ser region (aa 46-67), and a poly-Gly segment (aa 77-84), followed by a forkhead DNA binding domain (aa 99-190) and three homopolymeric "runs" involving His (aa 262-272), Gly (aa 301-306) and Ser (aa 312-315). Over aa 324-444, human FoxF2 shares 99% aa identity with mouse FoxF2.
