Researches have revealed that functional non-synonymous Single Nucleotide Polymorphism (nsSNPs) present in the Zinc-finger with UFM1-Specific Peptidase domain protein (ZUFSP) may be involved in genetic instability and carcinogenesis. For the first time, we employed in-silico approach using predictive tools to identify and validate potential nsSNPs that could be pathogenic. Our result revealed that 8 nsSNPs (rs 112738382, rs 140094037, rs 201652589, rs 201847265, rs 202076827, rs 373634906, rs 375114528, rs 772591104) are pathogenic after being subjected to rigorous filtering process. The structural impact of the nsSNPs on ZUFSP structure indicated that the nsSNPs affect the stability of the protein by lowering ZUFSP protein stability. Furthermore, conservation analysis showed that rs 201652589, rs 140094037, rs 201847265, and rs 772591104 were highly conserved. Interestingly, the protein-protein affinity between ZUFSP and Ubiquitin was altered rs 201652589, rs 140094037, rs 201847265, and rs 772591104 had a binding affinity of - 0.46, - 0.83, - 1.62, and - 1.12 kcal/mol respectively. Our study has been able to identify potential nsSNPs that could be used as genetic biomarkers for some diseases arising as a result of aberration in the ZUFSP structure, however, being a predictive study, the identified nsSNPs need to be experimentally investigated.
研究表明,锌指与 UFM1 特异性肽酶结构域蛋白(ZUFSP)中存在的功能非同义单核苷酸多态性(nsSNP)可能与遗传不稳定性和致癌作用有关。我们首次使用预测工具的计算机模拟方法来鉴定和验证可能具有致病性的潜在 nsSNP。我们的研究结果表明,经过严格的筛选过程,8 个 nsSNP(rs112738382、rs140094037、rs201652589、rs201847265、rs202076827、rs373634906、rs375114528、rs772591104)具有致病性。nsSNP 对 ZUFSP 结构的结构影响表明,这些 nsSNP 通过降低 ZUFSP 蛋白稳定性而影响蛋白的稳定性。此外,保守性分析表明,rs201652589、rs140094037、rs201847265 和 rs772591104 高度保守。有趣的是,ZUFSP 与泛素之间的蛋白质-蛋白质亲和力发生了变化,rs201652589、rs140094037、rs201847265 和 rs772591104 的结合亲和力分别为-0.46、-0.83、-1.62 和-1.12 kcal/mol。我们的研究已经能够鉴定出可能作为 ZUFSP 结构异常导致的某些疾病的遗传生物标志物的潜在 nsSNP,但作为预测性研究,需要对鉴定出的 nsSNP 进行实验验证。
