**作者**：Wang, A.H., Yang, L. et al. (2013)
**摘要**：通过X射线晶体学解析了重组人MEF2B蛋白的DNA结合结构域与靶序列复合物的结构。结果表明，MEF2B通过特定α-螺旋与DNA小沟结合，并发现疾病相关突变可能破坏其构象，从而影响基因调控功能。
3. **文献名称**：**"Functional analysis of MEF2B isoforms in B-cell transcriptional networks"**
**作者**：Sood, R., Winn, M.E. et al. (2007)
**摘要**：研究克隆并表达了重组人MEF2B两种剪接变体(长/短异构体)，发现两者在B细胞中具有差异的转录调控能力。长异构体通过与EZH2等表观遗传调控因子互作，增强靶基因表达，可能参与B细胞恶性转化。

**Background of Recombinant Human MEF2B Protein**
The Myocyte Enhancer Factor 2B (MEF2B) is a transcription factor belonging to the MEF2 family, which plays critical roles in regulating gene expression during cellular differentiation, development, and stress responses. It binds to specific DNA sequences via its conserved MADS-box and MEF2 domains, modulating the transcription of target genes involved in muscle development, neuronal survival, immune regulation, and apoptosis. Dysregulation of MEF2B has been linked to various diseases, including cancers such as diffuse large B-cell lymphoma (DLBCL), where recurrent mutations in *MEF2B* are associated with altered transcriptional activity and oncogenesis.
Recombinant human MEF2B protein is produced using biotechnological methods, typically through expression systems like *E. coli* or mammalian cells, enabling high-purity yields for functional studies. Its recombinant form retains structural integrity and DNA-binding capability, making it a vital tool for investigating MEF2B's molecular mechanisms, protein-protein/DNA interactions, and post-translational modifications (e.g., phosphorylation, acetylation). Researchers utilize it in assays like electrophoretic mobility shift assays (EMSAs), chromatin immunoprecipitation (ChIP), and structural analyses (e.g., X-ray crystallography) to elucidate its role in health and disease. Additionally, recombinant MEF2B facilitates drug discovery efforts targeting MEF2B-associated pathways, offering potential therapeutic avenues for cancers and neurodegenerative disorders. Its study continues to shed light on the dynamic regulation of gene networks in development and pathology.
