ABSTRACT
The SAM and HD domain containing protein 1 (Sterile alpha motif domain and HD domain-containing protein 1, SAMHD1) is a putative negative regulator of the antiviral innate immune response. It can significantly increase the antiviral immune response, mediates the interferon-induced inflammatory response involved in the host foreign-virus defense system. The early studies have focused on its gene mutations associated with Aicardi-Goutières syndrome (AGS), the latest study found that SAMHD1 as a potent dGTP-stimulated triphosphohydrolase restricts HIV-1 replication by hydrolyzing the majority of cellular dNTPs, thus inhibiting reverse transcription and viral complementary DNA (cDNA) synthesis. Auxiliary gene of HIV-2 and simian immunodeficiency virus (SIVsm / mac) encoding the Vpx protein can eliminate HIV-1 restriction. In recent years, the research on SAMHD1, mores forward rapidly this paper overviews the recent research progression related to the above fields.
