1 SAMHD1, a dGTP-regulated deoxyribonucleoside triphosphate (dNTP) triphosphohydrolase, down-regulates dNTP pools in terminally differentiated and quiescent cells, thereby inhibiting HIV-1 infection at the reverse transcription step. deoxyguanosine triphosphate SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
2 Further, we provide evidence that Vpx binding to SAMHD1 inhibits its catalytic activity and induces disassembly of a dGTP-dependent oligomer. deoxyguanosine triphosphate SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 1 Homo sapiens
