PHF13 (PHD Finger Protein 13) is a chromatin-associated protein implicated in epigenetic regulation and transcriptional control. It contains a conserved plant homeodomain (PHD), a structural motif known to recognize histone post-translational modifications, particularly trimethylated lysine 4 on histone H3 (H3K4me3), a marker of active gene promoters. PHF13 functions as a transcriptional co-regulator, interacting with chromatin-modifying complexes and RNA polymerase II to influence gene expression programs. Studies link it to stem cell pluripotency, cellular differentiation, and genome stability maintenance by facilitating DNA damage repair.
Recombinant PHF13 protein is engineered for in vitro and in vivo studies to dissect its molecular mechanisms. Typically produced in bacterial (e.g., E. coli) or mammalian expression systems, the recombinant protein retains functional domains necessary for chromatin binding and protein interactions. Purification tags (e.g., His-tag, GST) are often fused to facilitate isolation. Its applications include chromatin immunoprecipitation (ChIP), pull-down assays to map interactomes, and structural studies (e.g., X-ray crystallography) to resolve binding interfaces. Researchers also use it to explore PHF13's role in diseases; dysregulation of PHF13 is observed in cancers and neurodevelopmental disorders, suggesting therapeutic targeting potential. By enabling precise biochemical characterization, recombinant PHF13 advances understanding of epigenetic regulation and its disease implications.
