DPF3 (double PHD fingers 3) is a component of the BAF chr14 remodeling complex with multifaceted roles in cellular regulation. As a primary function, DPF3a cooperates with HDGFL2 to regulate myogenesis by mediating HDGFL2's interaction with the BAF complex, enabling recruitment of SMARCA4/BRG1 to myogenic gene promoters and increasing chr14 accessibility 1. Beyond myogenic differentiation, DPF3 exhibits context-dependent functions across diverse biological processes. In cancer biology, DPF3a promotes clear cell renal cell carcinoma metastasis by interacting with SNIP1 to form complexes with SMAD4 and p300 histone acetyltransferase, thereby activating TGF-β signaling and cell migration genes 2. Recent evidence reveals non-canonical functions during mitosis and ciliogenesis; DPF3 localizes to centrosomes and kinetochores during mitosis, and its loss causes kinetochore instability and chromosome 14, while it also localizes to centriolar satellites and is required for ciliogenesis and axoneme extension 3. Clinically, DPF3 polymorphisms (rs10129954) are significantly associated with male infertility, particularly azoospermia and oligozoospermia 45. Additionally, DPF3 genetic variants may contribute to melanoma susceptibility in horses 6, suggesting evolutionarily conserved roles in cancer predisposition.
