| Post Translational Modifications | Phosphorylation at Thr-592 by CDK1 acts as a switch to control deoxynucleoside triphosphate (dNTPase)-dependent and -independent functions. Phosphorylation at Thr-592 takes place in cycling cells: it reduces the stability of the homotetramer, impairing the dNTPase activity and subsequent ability to restrict infection by viruses. It also inhibits ability to suppress LINE-1 retrotransposon activity. In contrast, phosphorylation at Thr-592 promotes DNA end resection at stalled replication forks in response to DNA damage. (Microbial infection) Phosphorylation at Thr-592 by Epstein-Barr virus kinase BGLF4 and human cytomegalovirus/HCMV UL97 leads to a reduced level of dCTPase and dTTPase activity and the loss of viral restriction. (Microbial infection) Ubiquitinated following interaction with HIV-2 viral protein Vpx.Vpx promotes interaction and with a DCX (DDB1-CUL4-X-box) E3 ubiquitin ligase, leading to proteasomal degradation. |
| Function | 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, such as HIV-1: 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. Not able to restrict infection by HIV-2 virus.because restriction activity is counteracted by HIV-2 viral protein Vpx. In addition to virus restriction, dNTPase activity acts as a regulator of DNA precursor pools by regulating dNTP pools. Phosphorylation at Thr-592 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. |
