病毒需要宿主因子来支持其复制,并且这些因子中的遗传变异可以影响对传染病的易感性。人类细胞中的流感病毒复制依赖于ANP 32蛋白,其参与复制能力二聚流感病毒聚合酶(FluPol)复合物的组装。在这里,我们研究了人类Anp 32 A和Anp 32 B基因中天然存在的单核苷酸变体(SNV)。我们注意到Anp 32 B中的变体rs 182096718的频率高于任何一个基因中的其他变体。该SNV导致ANP 32 B中的D130 A取代,其支持FluPol活性的能力低于野生型ANP 32 B,并且以较低的亲和力结合FluPol。有趣的是,ANP 32 B-D130 A相对于野生型ANP 32 B发挥显性负效应,并干扰功能冗余的paradox ANP 32A。FluPol活性和病毒复制在表达野生型ANP 32A和突变体ANP 32 B-D130 A的CRISPR编辑的细胞中减弱。我们提出了一个模型,其中D130 A突变损害FluPol二聚体的形成,从而导致受损的复制。我们认为rs 182096718的纯合子和杂合子携带者可能对流感病毒具有一定的遗传保护作用。
Viruses require host factors to support their replication, and genetic variation in such factors can affect susceptibility to infectious disease. Influenza virus replication in human cells relies on ANP32 proteins, which are involved in assembly of replication-competent dimeric influenza virus polymerase (FluPol) complexes. Here, we investigate naturally occurring single nucleotide variants (SNV) in the human Anp32A and Anp32B genes. We note that variant rs182096718 in Anp32B is found at a higher frequency than other variants in either gene. This SNV results in a D130A substitution in ANP32B, which is less able to support FluPol activity than wild-type ANP32B and binds FluPol with lower affinity. Interestingly, ANP32B-D130A exerts a dominant negative effect over wild-type ANP32B and interferes with the functionally redundant paralogue ANP32A. FluPol activity and virus replication are attenuated in CRISPR-edited cells expressing wild-type ANP32A and mutant ANP32B-D130A. We propose a model in which the D130A mutation impairs FluPol dimer formation, thus resulting in compromised replication. We suggest that both homozygous and heterozygous carriers of rs182096718 may have some genetic protection against influenza viruses.
