The SAM domain of mouse SAMHD1 is critical for its activation and regulation

The sterile alpha-motif and histidine-aspartate domain-containing protein 1 (SAMHD1) is a dNTP phosphohydrolase that blocks HIV-1 infection by depleting cellular dNTPs. Here the authors present the structures of full-length mouse SAMHD1 in different nucleotide bound states and give insights into SAM...

Sumario:The sterile alpha-motif and histidine-aspartate domain-containing protein 1 (SAMHD1) is a dNTP phosphohydrolase that blocks HIV-1 infection by depleting cellular dNTPs. Here the authors present the structures of full-length mouse SAMHD1 in different nucleotide bound states and give insights into SAMHD1 activity regulation.
