**Background of Recombinant Human PMF1 Protein**
The Polyamine Modulated Factor 1 (PMF1) protein, encoded by the *PMF1* gene in humans, is a conserved nuclear protein implicated in diverse cellular processes, including chromatin remodeling, transcriptional regulation, and DNA repair. Initially identified for its interaction with polyamines, PMF1 is thought to modulate cellular responses to these critical organic cations involved in proliferation and differentiation. Structurally, PMF1 contains a predicted coiled-coil domain and nuclear localization signals, suggesting roles in protein-protein interactions and nuclear transport.
PMF1 has emerged as a key player in the DNA damage response (DDR) pathway, interacting with proteins like ALKBH2 to mediate repair of alkylation damage. Additionally, studies link PMF1 to transcriptional regulation through its association with chromatin-modifying complexes, such as the Polycomb Repressive Complex 2 (PRC2), influencing histone H3K27 trimethylation and gene silencing. Dysregulation of PMF1 has been implicated in disease contexts; for instance, *PMF1* mutations or altered expression are associated with neurodevelopmental disorders, cancer progression, and impaired spermatogenesis.
Recombinant human PMF1 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) for functional studies. Its purified form enables biochemical and structural analyses, including interactions with DNA or partner proteins, and exploration of its role in DDR or epigenetic regulation. Research on recombinant PMF1 continues to shed light on its molecular mechanisms and potential therapeutic applications in diseases linked to genomic instability or transcriptional dysregulation.
