Product Type: Chemical
Enhanced Validation-Orthogonal RNAseq Confirmation Immunohistochemistry analysis in human cerebral cortex and liver tissues using HPA018864 antibody. Corresponding FOXK1 RNA-seq data are presented for the same tissues.
Enhanced Validation-By Independent Antibodies Immunohistochemical staining of human cerebral cortex, liver, lymphoid tissues and testis using Anti-FOXK1 antibody HPA018864 (A) shows similar protein distribution across tissues to independent antibody HPA017998 (B).
ChIP-Exo-Seq composite graph for Anti-FOXK1 (HPA018864, Lot 000020125) tested in K562 cells. Strand-specific reads (blue: forward, red: reverse) and IgG controls (black: forward, grey: reverse) are plotted against the distance from a composite set of reference binding sites. The antibody exhibits robust target enrichment compared to a non-specific IgG control and precisely reveals its structural organization around the binding site. Data generated by Prof. B. F. Pugh´s Lab at Cornell University. *Please note not all antibody batches are validated for use in ChIP applications.
Immunohistochemistry Immunohistochemical staining of human cerebral cortex shows moderate to strong nuclear positivity in neurons.
Immunohistochemistry Immunohistochemical staining of human testis shows moderate to strong nuclear positivity in cells in seminiferous ducts.

| Application: | All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information. |
| Biochem/physiol Actions: | Forkhead box protein K1 (FOXK1) is involved in carcinogenesis and embryogenesis. FOXK1 is up-regulated in colorectal cancers. It binds dishevelled (DVL) and translocates it to the nucleus, thereby activating Wnt/β-catenin signaling. FOXK1 regulates many genes involved in cell cycle, including DHFR (dihydrofolate reductase), TYMS (thymidylate synthase), GSDMD (gasdermin-D), and TFDP1 (transcription factor Dp-1). Absence of FOXK1 decreases cell proliferation rates. |
| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
| General description: | The gene FOXK1 (forkhead box protein K1) is mapped to human chromosome 7p22.1. It belongs to forkhead-box (FOX) family transcription factors. FOXK1 is present in immature tissues of brain, eye, heart, lung and thymus. However, in adults FOXK1 is particularly present in malignant tissues (brain, colon and lymph node). |
