The COVID-19 pandemic prompted rapid research on SARS-CoV-2 pathogenicity. Consequently, new data can be used to advance the molecular understanding of SARS-CoV-2 infection. The present bioinformatics study discusses the "spikeopathy" at the molecular level and focuses on the possible post-transcriptional regulation of the SARS-CoV-2 spike protein S1 subunit in the host cell/tissue. A theoretical protein-RNA recognition code was used to check the compatibility of the SARS-CoV-2 spike protein S1 subunit with mRNAs in the human transcriptome (1-L transcription). The principle for this method is elucidated on the defined RNA binding protein GEMIN5 (gem nuclear organelle-associated protein 5) and RNU2-1 (U2 spliceosomal RNA). Using the method described here, it was shown that 45% of the genes/proteins identified by 1-L transcription of the SARS-CoV-2 spike protein S1 subunit are directly linked to COVID-19, 39% are indirectly linked to COVID-19, and 16% cannot currently be associated with COVID-19. The identified genes/proteins are associated with stroke, diabetes, and cardiac injury.
新冠疫情促使人们对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的致病性展开快速研究。因此,新的数据可用于加深对SARS-CoV-2感染的分子理解。本生物信息学研究在分子水平上探讨了“刺突病变”,并聚焦于宿主细胞/组织中SARS-CoV-2刺突蛋白S1亚基可能的转录后调控。使用一种理论性的蛋白质-RNA识别密码来检查SARS-CoV-2刺突蛋白S1亚基与人类转录组(1-L转录)中的mRNA的兼容性。该方法的原理在已定义的RNA结合蛋白GEMIN5(宝石核细胞器相关蛋白5)和RNU2-1(U2剪接体RNA)上得到阐明。使用此处描述的方法表明,通过SARS-CoV-2刺突蛋白S1亚基的1-L转录鉴定出的基因/蛋白质中,45%与新冠直接相关,39%与新冠间接相关,16%目前无法与新冠建立联系。所鉴定出的基因/蛋白质与中风、糖尿病和心脏损伤有关。
