Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of the on-going global pandemic of coronavirus disease 2019 (COVID-19) that continues to pose a significant threat to public health worldwide. SARS-CoV-2 encodes four structural proteins namely membrane, nucleocapsid, spike, and envelope proteins that play essential roles in viral entry, fusion, and attachment to the host cell. Extensively glycosylated spike protein efficiently binds to the host angiotensin-converting enzyme 2 initiating viral entry and pathogenesis. Reverse transcriptase polymerase chain reaction on nasopharyngeal swab is the preferred method of sample collection and viral detection because it is a rapid, specific, and high-throughput technique. Alternate strategies such as proteomics and glycoproteomics-based mass spectrometry enable a more detailed and holistic view of the viral proteins and host-pathogen interactions and help in detection of potential disease markers. In this review, we highlight the use of mass spectrometry methods to profile the SARS-CoV-2 proteome from clinical nasopharyngeal swab samples. We also highlight the necessity for a comprehensive glycoproteomics mapping of SARS-CoV-2 from biological complex matrices to identify potential COVID-19 markers.
严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)是导致 2019 年冠状病毒病(COVID-19)全球大流行的原因,它继续对全球公共卫生构成重大威胁。SARS-CoV-2 编码 4 种结构蛋白,即膜蛋白、核衣壳蛋白、刺突蛋白和包膜蛋白,它们在病毒进入、融合和与宿主细胞附着中发挥重要作用。高度糖基化的刺突蛋白有效地与宿主血管紧张素转换酶 2 结合,启动病毒进入和发病机制。鼻咽拭子的逆转录酶聚合酶链反应是首选的样本采集和病毒检测方法,因为它是一种快速、特异和高通量的技术。替代策略,如基于蛋白质组学和糖蛋白质组学的质谱分析,能够更详细和全面地了解病毒蛋白和宿主-病原体相互作用,并有助于检测潜在的疾病标志物。在这篇综述中,我们强调了使用质谱方法来分析临床鼻咽拭子样本中的 SARS-CoV-2 蛋白质组。我们还强调了从生物复杂基质中对 SARS-CoV-2 进行全面糖蛋白质组学作图以鉴定潜在的 COVID-19 标志物的必要性。
