Recombinant human DPF2 (Double PHD Fingers 2) protein, also known as REQ or UBID4. is a chromatin-associated protein involved in transcriptional regulation and chromatin remodeling. It belongs to the d4-family of zinc finger proteins, characterized by two tandem plant homeodomain (PHD) fingers that mediate interactions with histones, particularly recognizing post-translational modifications like H3K14ac and H3K4me3. DPF2 acts as a key subunit of the BAF (BRG1/BRM-associated factor) chromatin-remodeling complex, facilitating nucleosome repositioning to modulate gene expression during development and differentiation. Dysregulation of DPF2 is linked to cancers (e.g., leukemia, neuroblastoma) and developmental disorders such as Coffin-Siris syndrome. Its recombinant form, produced via bacterial or mammalian expression systems, is widely used to study molecular interactions, epigenetic mechanisms, and screen potential therapeutic compounds targeting chromatin remodeling pathways. Studies highlight its role in neural crest development, immune response, and hematopoietic stem cell maintenance.
