UTF1 (undifferentiated embryonic cell transcription factor 1) is a 47‑57 kDa transcriptional coactivator. It is expressed mainly in embryonic stem cells, is regulated by Oct-3/4, and promotes rapid cell proliferation. Human UTF1 is a 341 amino acid (aa) phosphoprotein. It is rich in Proline and Arginine residues and contains a
C‑terminal Leu-zipper (aa 286‑313) that is known to interact with the metal-binding motif of ATF-2. Unlike mouse UTF1 which contains an alternate start site at Met43, human UTF1 lacks this Methionine and shows only one isoform. Over amino acids 44‑153, human UTF1 shares 81% aa sequence identity with mouse UTF1.

Scientific Data Images for Human UTF1 Antibody
UTF1 in BG01V Human Embryonic Stem Cells.
UTF1 was detected in immersion fixed BG01V human embryonic stem cells using Goat Anti-Human UTF1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3958) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001). SSEA4 was also detected using Mouse Anti-Human SSEA4 Monoclonal Antibody (Catalog # MAB1435) and stained using the NorthernLights™ 493-conjugated Anti-Goat IgG Secondary Antibody (green; Catalog # NL003). Cells were counterstained with DAPI (blue). Specific staining of UTF1 was localized to nuclei. View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips.
