Guanine-containing ssDNA and RNA induce dimeric and tetrameric SAMHD1 in cryo-EM and binding studies

B. Orris, M. W. Sung, S. Bhat, Y. Xu, K. W. Huynh, S. Han, D. C. Johnson, B. Bosbach, D. J. Shields, J. T. Stivers

This study shows that guanine-containing ssDNA and RNA induce dimeric or tetrameric SAMHD1, with tetramers being inactive for dNTPase and RNase activity.

Phosphorylation of SAMHD1 Thr592 increases C-terminal domain dynamics, tetramer dissociation, and ssDNA binding kinetics

B. Orris, K. W. Huynh, M. Ammirati, S. Han, B. Bolanos, J. Carmody, M. D. Petroski, B. Bosbach, D. J. Shields, J. T. Stivers

This study shows that phosphorylation of SAMHD1 at Thr592 increases tetramer dynamics and ssDNA binding, leading to rapid inactivation of dNTPase activity at stalled replication forks.
