DPPA5 (Developmental Pluripotency-Associated 5), also known as embryonic stem cell-associated transcript 5 (ECAT5), is a gene prominently expressed in early embryonic development and pluripotent stem cells. It belongs to the DPPA gene family, which includes key regulators of cellular pluripotency and epigenetic reprogramming. DPPA5 encodes a small, intrinsically disordered protein with a conserved N-terminal domain and a charged C-terminal region, though its precise molecular mechanism remains under investigation. Studies suggest it plays a role in maintaining the naive pluripotent state of embryonic stem cells by interacting with chromatin modifiers and transcriptional networks, potentially stabilizing the epigenetic landscape required for self-renewal.
Recombinant DPPA5 protein is produced using heterologous expression systems (e.g., E. coli or mammalian cells) and purified for functional studies. Its disordered structure often necessitates specific solubility tags or fusion partners during production. Research applications include investigating early embryogenesis, cellular reprogramming, and pluripotency regulation. DPPA5 has been implicated in enhancing somatic cell reprogramming efficiency when combined with Yamanaka factors, highlighting its therapeutic potential in regenerative medicine. Additionally, its expression is tightly restricted to pluripotent cells, making it a valuable biomarker for assessing stem cell quality or detecting residual undifferentiated cells in differentiated cell therapies. Recent studies also explore its role in cancer biology, as aberrant expression has been observed in certain malignancies. However, challenges in studying its unstructured nature and precise molecular targets continue to drive methodological innovations in protein engineering and interactome analysis.
