Schlafen 11 (SLFN11) is a member a family of proteins that can be found in mammals. Members of this family are involved in important functions. SLFN11 in particular has been identified as a restriction factor for several evolutionarily disparate viruses such as HIV-1 and Flaviviruses and to play an important role in DNA repair, sensitizing cells to chemotherapy. Despite its relevance SLFN11 remains largely uncharacterized. The aim of this research was to achieve a more comprehensive understanding the regulation mechanism of SLFN 11 expression. Before our research, it was only known that type I interferon (IFN) regulates SLFN11 levels. However, we have demonstrated that SLFN11 expression is controlled by type I interferon-dependent and -independent mechanisms. Among the latter protein kinase C- and calcium-regulated-signaling pathways are of relevance. More important, we have also established that during viral infection-induced SLFN11 upregulation the relevance of these mechanisms vary depending on the ability of the virus to block the type I IFN system. Therefore, our findings have revealed the complexity of the regulation of the expression of this innate immune protein and evidenced important gaps in our knowledge.
