DMRTA2 (Doublesex and mab-3 related transcription factor A2) is a member of the DMRT protein family, which shares a conserved zinc finger-like DNA-binding domain (DM domain) implicated in developmental regulation and cell fate determination. In humans, DMRTA2 plays critical roles in embryonic development, particularly in neurogenesis and organogenesis. It regulates the expression of target genes by binding to specific DNA sequences, influencing processes such as cell proliferation, differentiation, and apoptosis. Structurally, the protein contains an N-terminal zinc-finger domain essential for DNA interaction and a C-terminal dimerization domain. Its expression is tightly controlled temporally and spatially, with notable activity in the developing brain, limbs, and sensory organs.
Recombinant human DMRTA2 protein is artificially produced using expression systems like *E. coli* or mammalian cells, enabling functional studies without isolating it from native tissues. Researchers employ it to investigate its transcriptional regulatory mechanisms, protein-protein interactions, and role in developmental disorders or cancers. Dysregulation of DMRTA2 has been linked to neurodevelopmental abnormalities and tumorigenesis, making it a potential therapeutic target. The recombinant form’s purity and activity are validated for applications in electrophoretic mobility shift assays (EMSA), chromatin immunoprecipitation (ChIP), and *in vitro* differentiation models. Ongoing research aims to clarify its interplay with signaling pathways like Wnt or Notch, which may uncover novel insights into tissue patterning and disease pathways.
