Undifferentiated embryonic cell transcription factor 1 (UTF1) is a chromatin-associated protein encoded by the *UTF1* gene in humans, functioning as a transcriptional regulator involved in embryonic development and stem cell pluripotency. It interacts with chromatin-modifying complexes, including Polycomb repressive complexes, to modulate gene expression epigenetically. UTF1 is highly expressed in embryonic stem cells (ESCs), where it plays a dual role: maintaining pluripotency by repressing differentiation genes and safeguarding genome stability through stress response regulation. Its dynamic chromatin binding, influenced by external signaling, allows rapid transcriptional adaptation during cell fate transitions. Structurally, UTF1 contains a conserved N-terminal region for chromatin interaction and a disordered C-terminal domain. Recombinant human UTF1 protein, often produced via *E. coli* or mammalian expression systems, enables *in vitro* studies of its molecular mechanisms. Dysregulation of UTF1 is linked to cancers, particularly germ cell tumors, highlighting its potential as a therapeutic target. Research on recombinant UTF1 advances understanding of stem cell biology, epigenetic regulation, and disease pathogenesis.
