人类内源性逆转录病毒(HERV)是古代逆转录病毒感染的胚系嵌合前病毒片段,约占人类基因组的8%。我们在生理学上对HERV的理解主要围绕着它们的非编码功能,而它们的蛋白质编码能力几乎还没有确定。因此,我们将生物信息学管道“hervQuant”应用于健康组织的高分辨率核糖体分析,以提供翻译上活跃的HERV的全面概述。我们发现,在不同的组织特异性图谱中,HERV占所有翻译的0.1-0.4%。总体而言,我们的研究进一步支持了HERV在健康组织中被积极翻译,为人类蛋白质组提供逆转录病毒起源的序列的说法。网上版载有补充材料,可在10.1186/s12864-023-09909-x查阅。
Human endogenous retroviruses (HERVs) are the germline embedded proviral fragments of ancient retroviral infections that make up roughly 8% of the human genome. Our understanding of HERVs in physiology primarily surrounds their non-coding functions, while their protein coding capacity remains virtually uncharacterized. Therefore, we applied the bioinformatic pipeline “hervQuant” to high-resolution ribosomal profiling of healthy tissues to provide a comprehensive overview of translationally active HERVs. We find that HERVs account for 0.1–0.4% of all translation in distinct tissue-specific profiles. Collectively, our study further supports claims that HERVs are actively translated throughout healthy tissues to provide sequences of retroviral origin to the human proteome.
