SAMHD1 SHAPES DEOXYNUCLEOTIDE TRIPHOSPHATE HOMEOSTASIS BY INTERCONNECTING THE DEPLETION AND BIOSYNTHESIS OF DIFFERENT DNTPS

SAMHD1 shapes deoxynucleotide triphosphate homeostasis by interconnecting the depletion and biosynthesis of different dNTPs

Abstract SAMHD1 is a dNTPase that impedes replication of HIV-1 in myeloid cells and resting T lymphocytes.Here we elucidate the substrate activation mechanism of SAMHD1, which involves dNTP binding at allosteric sites and transient tetramerization.Our findings reveal that tetramerization alone is insufficient to promote dNTP hydrolysis; instead, th

Association of childhood BMI trajectory with post-adolescent and adult lung function is mediated by pre-adolescent DNA methylation

Abstract Background Body mass index (BMI) has been shown to be associated with lung function.Recent findings showed that DNA methylation (DNAm) variation is likely to be a consequence of changes in BMI.However, whether DNAm mediates the association of BMI with lung function is unknown.We examined the mediating role of DNAm on the association of pre
