Abstract

, which causes life-threatening cerebral malaria has rapidly gained resistance against most frontline anti-malarial drugs, thereby generating an urgent need to develop novel therapeutic approaches. Conducting in-depth investigations on in its native form is challenging, thereby necessitating the requirement of an efficient model system. In line, mounting evidence suggests that retains both conformational and functional properties of proteins, however, the true potential of as a host system is not fully explored. In the present study, we have exploited comparative genomics as a tool to extract, compare, and curate the extensive data available on the organism-specific databases to evaluate if can be established as a prime model system for functional characterization of genes. Through comprehensive analysis, we report that despite the presence of adaptation-specific genes, the two display noteworthy conservation in the housekeeping genes, signaling pathway components, transcription regulators, and post-translational modulators. Furthermore, through orthologue analysis, the known, potential, and novel drug target genes of were found to be significantly conserved in . Our findings advocate that can be employed to express and functionally characterize difficult-to-express genes.

摘要

导致危及生命的脑型疟疾的[病原体名称]已迅速对大多数一线抗疟药物产生耐药性,因此迫切需要开发新的治疗方法。对处于天然形式的[病原体名称]进行深入研究具有挑战性,因此需要一个高效的模型系统。相应地,越来越多的证据表明[替代模型名称]保留了[病原体名称]蛋白质的构象和功能特性,然而,[替代模型名称]作为宿主系统的真正潜力尚未得到充分探索。在本研究中,我们利用比较基因组学作为工具,提取、比较和整理特定生物体数据库中可用的大量数据,以评估是否可以将[替代模型名称]建立为用于[病原体名称]基因功能表征的主要模型系统。通过全面的[分析名称]分析,我们报告称,尽管存在适应特异性基因,但两者在内含子基因、信号通路成分、转录调节因子和翻译后调节剂方面显示出显著的保守性。此外,通过直系同源物分析,发现[病原体名称]的已知、潜在和新型药物靶基因在[替代模型名称]中显著保守。我们的研究结果表明,[替代模型名称]可用于表达和功能表征难以表达的[病原体名称]基因。
