靶點詳情

  • 功能：
    Protein that acts both as a host restriction factor involved in defense response to virus and as a regulator of DNA end resection at stalled replication forks. Has deoxynucleoside triphosphate (dNTPase) activity, which is required to restrict infection by viruses: dNTPase activity reduces cellular dNTP levels to levels too low for retroviral reverse transcription to occur, blocking early-stage virus replication in dendritic and other myeloid cells. Likewise, suppresses LINE-1 retrotransposon activity. In addition to virus restriction, dNTPase activity acts as a regulator of DNA precursor pools by regulating dNTP pools. Phosphorylation at Thr-634 acts as a switch to control dNTPase-dependent and -independent functions: it inhibits dNTPase activity and ability to restrict infection by viruses, while it promotes DNA end resection at stalled replication forks. Functions during S phase at stalled DNA replication forks to promote the resection of gapped or reversed forks: acts by stimulating the exonuclease activity of MRE11, activating the ATR-CHK1 pathway and allowing the forks to restart replication. Its ability to promote degradation of nascent DNA at stalled replication forks is required to prevent induction of type I interferons, thereby preventing chronic inflammation. Ability to promote DNA end resection at stalled replication forks is independent of dNTPase activity. Enhances immunoglobulin hypermutation in B-lymphocytes by promoting transversion mutation.

    1. SAMHD1 inhibits NF-kappaB activation by interacting with NF-kappaB1/2 and reducing phosphorylation of the NF-kappaB inhibitory protein IkappaBalpha. SAMHD1 also interacts with the inhibitor-kappaB kinase epsilon (IKKepsilon) and IFN regulatory factor 7 (IRF7), leading to the suppression of the IFN-I induction pathway by reducing IKKepsilon-mediated IRF7 phosphorylation. SAMHD1 down-regulates innate immune responses to ... PMID: 29610295
    2. SAMHD1's restriction of dNTP supply enhances AID's mutagenicity and that the evolution of Ig hypermutation included the repurposing of antiviral mechanisms based on dNTP starvation. PMID: 29669924
    3. SAMHD1 crystal structure delineates the SAMHD1 allosteric activation process that governs SAMHD1 enzymatic activities. PMID: 29379009
    4. provide genetic evidence that cell-autonomous control of lentivirus infection in myeloid cells by SAMHD1 limits virus-induced production of interferons and the induction of co-stimulatory markers PMID: 27477283
    5. These data support a model in which SAMHD1 catalytic activity is regulated through tetramer stabilization by the carboxyl-terminal tail, phosphorylation destabilizing the complexes and inactivating the enzyme. ISF2 may serve to reduce the dNTP pool to very low levels as a means of restricting virus replication. PMID: 27920203
    6. These observations suggest that heterozygous cancer-associated SAMHD1 mutations increase mutation rates in cancer cells. PMID: 27071091
    7. SAMHD1 in the mouse blocks retroviral infection at the level of reverse transcription and is regulated through cell cycle-dependent phosphorylation. PMID: 26667483
    8. phosphorylation of mSAMHD1 at T634 by CDK1/2 negatively regulates its HIV-1 restriction in differentiated cells, but does not affect its murine leukemia virus restriction in dividing cells. PMID: 26580513
    9. SAMHD1 restricts HIV-1 replication and regulates interferon production in mouse myeloid cells. PMID: 24586870
    10. Allosteric regulation by dATP and dTTP works similarly in human and mouse SAMHD1. PMID: 24828500
    11. SAMHD1 decreases dNTP pool in murine cells, restricts retroviral replication and regulates type I IFN production. PMID: 23972988
    12. SAMHD1 can restrict lentiviruses in vivo and that nucleotide starvation is an evolutionarily conserved antiviral mechanism. PMID: 23872947
    13. there are several Vpx residues required for SAMHD1 degradation PMID: 23076149
    14. Vpx targets SAMHD1 for degradation in a viral strategy to control cellular deoxynucleotide levels for efficient replication PMID: 22069334
