Target Function Transcription factor that is involved in embryonic development, establishment of tissue-specific gene expression and regulation of gene expression in differentiated tissues. Is thought to act as a 'pioneer' factor opening the compacted chromatin for other proteins through interactions with nucleosomal core histones and thereby replacing linker histones at target enhancer and/or promoter sites. Binds DNA with the consensus sequence 5'-[AC]A[AT]T[AG]TT[GT][AG] [CT]T[CT]-3' (By similarity). In embryonic development is required for notochord formation. Involved in the development of multiple endoderm-derived organ systems such as the liver, pancreas and lungs; FOXA1 and FOXA2 seem to have at least in part redundant roles. Originally discribed as a transcription activator for a number of liver genes such as AFP, albumin, tyrosine aminotransferase, PEPCK, etc. Interacts with the cis-acting regulatory regions of these genes. Involved in glucose homeostasis; regulates the expression of genes important for glucose sensing in pancreatic beta-cells and glucose homeostasis. Involved in regulation of fat metabolism. Binds to fibrinogen beta promoter and is involved in IL6-induced fibrinogen beta transcriptional activation. Sequence similarities Contains 1 fork-head DNA-binding domain. Post-translational modifications Phosphorylation on Thr-156 abolishes binding to target promoters and subsequent transcription activation upon insulin stimulation. Cellular localization Nucleus. Cytoplasm. Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner and in response to insulin signaling via AKT1 is exported from the nucleus. Anti-FOXA2 antibody images Immunohistochemistry. Adult mouse lung was embedded in paraffin and stained with ab40874 (1:2000 dilution). FOXA2 was visualized by DAB (black color) and counterstained with Nuclear Fast Red (pink Immunohistochemistry (Formalin/PFA-fixed color). Magnification 20x. paraffin-embedded sections) - FOXA2 antibody (ab40874) 2 ab40874 at a 1/1000 dilution staining FOXA2 in rat midbrain tissue sections by Immunohistochemistry (frozen sections) incubated for 16 hours at 25°C. PFA fixed. Blocked with 5% serum for 1 hour at 25°C. Secondary used at 1/200 polyclonal Goat Immunohistochemistry (Frozen sections) - FOXA2 anti-rabbit conjugated to Alexa Fluor 488. antibody (ab40874) DAPI staining (blue), FOXA2 staining (green). This image is courtesy of an anonymous abreview. ab40874 staining FOXA2 in mouse embryo by Immunohistochemistry (PFA perfusion fixed frozen sections). Embryos were isolated, fixed for 20 minutes in 2% PFA in PBS, and then permeabilized in 0.1% Triton X-100 in 0.1 M glycine pH 8.0. After blocking in 10% FCS, 3% goat serum, 0.1% BSA, 0.1% Tween 20 for 2 hours, embryos were incubated with the primary antibody overnight at 4°C in blocking solution. After several washes in PBS containing 0.1% Tween-20 Immunohistochemistry (PFA perfusion fixed (PBST) samples were incubated with Donkey frozen sections) - FOXA2 antibody (ab40874) anti-rabbit 488 secondary antibodies.

The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab40874, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Immunocytochemistry/ Immunofluorescence FOXA2 antibody (ab40874) Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
