Protein

Deoxynucleoside triphosphate triphosphohydrolase SAMHD1

Gene

SAMHD1

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Host restriction nuclease that blocks early-stage virus replication in dendritic and other myeloid cells. Likewise, suppresses LINE-1 retrotransposon activity. May function by reducing the cellular dNTP levels to levels too low for retroviral reverse transcription to occur. May play a role in mediating proinflammatory responses to TNF-alpha signaling.4 Publications

Catalytic activityi

dNTP + H2O = Deoxynucleoside + triphosphate.2 Publications

Cofactori

Zn2+1 PublicationNote: Binds 1 zinc ion per subunit.1 Publication

Enzyme regulationi

Allosterically stimulated by dGTP which binds in a cleft at the interface of the homodimer and promotes the formation of highly active homotetramers. Each allosteric site binds two molecules of dGTP (dGTP1 and dGTP 2) between adjoining subunits. Not activated by dATP, dCTP and dTTP.3 Publications

Involvement in diseasei

Aicardi-Goutieres syndrome 5 (AGS5) [MIM:612952]: A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood.3 Publications
Note: The disease is caused by mutations affecting the gene represented in this entry.
