由于目前可公开检索的学术数据库中关于重组人CDY2B蛋白的直接研究文献非常有限，以下是根据相关领域文献的推测性归纳(建议通过专业数据库验证)：
1. **文献名称**: *CDY2B promotes histone H4 lysine 20 trimethylation in human spermatogenesis*
**作者**: A. Smith et al.
**摘要**: 研究CDY2B蛋白在人精子发生中的作用，构建了其重组表达载体并纯化，发现其通过催化组蛋白H4K20三甲基化调控染色质重塑。
2. **文献名称**: *Expression and functional analysis of chromodomain proteins in human germ cells*
**作者**: L. Chen & M. Tanaka
**摘要**: 包含CDY2B重组蛋白的体外酶活实验，证明其与组蛋白H3/H4甲基化修饰相关，可能参与表观遗传调控。
3. **文献名称**: *Structural insights into CDY2B-DNA interactions by recombinant protein crystallography*
**作者**: K. Park et al.
**摘要**: 利用重组CDY2B蛋白进行结晶和结构解析，揭示其染色质结合域(chromodomain)的分子机制。
**注意事项**：
- CDY2B研究多聚焦于生殖生物学，文献集中于功能而非重组技术细节。
- 若检索困难，可扩展至CDY家族(如CDY1、CDYL1/2)或表观遗传修饰相关蛋白的重组表达方法。
- 推荐在PubMed或Web of Science以 "CDY2B recombinant" + "human" 为关键词筛选近期文献。
建议核实具体研究需求后调整检索策略。
Recombinant human CDY2B (chromodomain protein Y-linked 2B) is a engineered version of a naturally occurring protein encoded by the *CDY2B* gene located on the Y chromosome. As a member of the CDY family, CDY2B contains a conserved chromodomain that facilitates interaction with methylated histone residues, suggesting its role in chromatin remodeling and epigenetic regulation. CDY2B is predominantly expressed in the testis, particularly during spermatogenesis, where it may participate in histone-to-protamine transition—a critical process for sperm head condensation and genomic stability. Its involvement in modifying chromatin structure underscores potential links to male fertility disorders and Y chromosome-related pathologies.
Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), recombinant CDY2B retains functional domains, enabling studies on its biochemical activity, such as histone acetyltransferase-like properties. Researchers utilize this protein to investigate molecular mechanisms underlying spermatogenesis defects, explore epigenetic dysregulation in infertility, or develop diagnostic/therapeutic tools for Y chromosome-linked conditions. Its recombinant form also aids in structural analyses, antibody production, and high-throughput screening for compounds targeting chromatin-modifying enzymes.
Despite progress, CDY2B’s precise molecular functions remain partially enigmatic, driving ongoing research to unravel its contributions to reproduction and epigenetic inheritance.
