Mouse Anti-UTF1 (Undifferentiated Embryonic Cell Transcription Factor 1)
Undifferentiated transcription factor-1 (UTF-1) is used as marker for the undifferentiated state of pluripotent stem cells.UTF1 is a chromatin-associated protein with core histone-like properties. UTF1 further acts as a transcriptional repressor and is required for proper differentiation of pluripotent cells.
UTF1 (undifferentiated embryonic cell transcription factor 1) is a 47-57kD 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 341aa phosphoprotein. It is rich in Proline and Arginine residues and contains a C-terminal Leu-zipper (aa286-313) that is known to interact with the metal-binding motif of ATF-2. Unlike mouse UTF1 which contains an alternate start site at Met 43, human UTF1 lacks this Methionine and shows only one isoform. Over aa44-153, human UTF1 shares 81% aa sequence identity with mouse UTF1.
