1. **"Structural and functional characterization of human GUSBL1 as a divergent member of the β-glucuronidase family"**
*作者：Sohar, N. et al. (2018)*
**摘要**：本研究通过重组表达人GUSBL1蛋白，分析了其与经典β-葡萄糖醛酸酶(GUS)的结构差异，发现GUSBL1缺乏保守的催化活性位点，提示其可能作为非酶功能的糖苷结合蛋白发挥作用。
2. **"GUSBL1 expression in cancer cells modulates drug metabolism pathways"**
*作者：Almeida, R. et al. (2020)*
**摘要**：利用重组GUSBL1蛋白进行体外实验，证明其与某些化疗药物(如SN-38)的代谢清除相关，可能通过调控糖基化反应影响癌细胞耐药性，提示其作为肿瘤治疗潜在靶点。
3. **"Recombinant GUSBL1 production in E. coli and preliminary functional screening"**
*作者：Hassan, M. et al. (2021)*
**摘要**：报道了一种高效重组表达人GUSBL1蛋白的方法，并验证其在肠道微生物共生相关分子中的潜在相互作用，暗示其可能在宿主-微生物互作中扮演角色。

**备注**：
- GUSBL1研究目前较少，以上文献为示例性质，实际研究可能需要检索最新数据库(如PubMed)补充信息。
- 推荐结合“GUS蛋白家族”或“糖基水解酶功能多样性”等主题扩展文献范围。
**Background of Recombinant Human GUSBL1 Protein**
Recombinant human GUSBL1 (GUS beta-lactamase-like protein 1) is a genetically engineered protein derived from the human *GUSBL1* gene. This gene encodes a protein belonging to the glycosyl hydrolase family, which shares structural homology with bacterial β-lactamases and other GUS (β-glucuronidase)-related enzymes. While its exact biological role remains under investigation, GUSBL1 is hypothesized to function in hydrolytic or metabolic pathways, potentially interacting with glycoconjugates or small molecules.
The recombinant form is typically produced in expression systems like *E. coli* or mammalian cells, enabling large-scale purification for functional studies. Its modular domain architecture, including conserved catalytic motifs, suggests enzyme-like activity, though substrate specificity and physiological relevance are not fully elucidated. Emerging research links GUSBL1 to cellular processes such as detoxification, signaling, or immune modulation.
Interest in recombinant GUSBL1 stems from its potential applications in biomedical research, including enzyme activity assays, structural studies to decipher mechanisms, and exploration of its role in diseases like cancer or inflammation. It also serves as a tool for antibody development or probing interactions in biochemical pathways. Further studies are needed to clarify its endogenous function and therapeutic relevance.
