SAMHD1 may play a role in regulation of the innate immune response. Additionally we are shipping SAMHD1 Antibodies (141) and SAMHD1 Kits (5) and many more products for this protein.
Showing 4 out of 4 products:
MiR (show MLXIP Proteins)-181a is an important mediator for interferons-induced SAMHD1 expression in astrocytes and microglia, but not for inhibition of HIV-1 infection induced by IFN-alpha (show IFNA Proteins).
SAMHD1 is active in HIV-1 permissive cells, does not modify susceptibility to HIV-1 infection but strongly affects sensitivity to nucleoside inhibitors.
expression of p21 (show CDKN1A Proteins) potentially can contribute to inhibition of HIV-1 replication in monocyte-derived dendritic cells through multiple mechanisms. p21 (show CDKN1A Proteins) decreased size of the intracellular dNTP pool; p21 (show CDKN1A Proteins) prevented SAMHD1 phosphorylation and promoted SAMHD1 dNTPase-independent antiviral activity
Studies indicate the ambiguous properties of sterile alpha motif and histidine/aspartic acid domain-containing protein 1 (SAMHD1) as both an inhibitor of uncontrolled proliferation and a resistance factor limiting the efficacy of anticancer treatments.
stereoselective 2' substitutions that reveal nucleotide substrate specificity for SAMHD1, and a novel inhibitory mechanism for the dNTPase activity of SAMHD1, are reported.
Allosteric regulation of SAMHD1 has been uncovered through molecular dynamics simulations.
Cell cycle-associated changes of proteins are induced by activation of the Raf (show RAF1 Proteins)/MEK (show MAP2K1 Proteins)/ERK (show EPHB2 Proteins) kinase cascade, culminating in upregulation of CDK1 (show CDK1 Proteins) with subsequent SAMHD1 T592 phosphorylation and deactivation of its antiviral activity.
SAMHD1 acts as an inhibitor in cutaneous T-cell lymphoma cell growth.
miR (show MLXIP Proteins)-181 is an important regulator of SAMHD1 protein expression in neoplastic CD4 (show CD4 Proteins)+ T-cells, likely through a mechanism of translational inhibition
the mechanisms by which SAMHD1 is phosphorylated and suggest the contribution of cyclin (show PCNA Proteins) binding to SAMHD1 expression and stability in dividing cells.
Data suggest that zebrafish may represent a system for studying the relationship between type I interferon (show IFNA Proteins) (IFN) signaling and a loss of deoxynucleoside triphosphate triphosphohydrolase SAMHD1 activity.
provide genetic evidence that cell-autonomous control of lentivirus infection in myeloid cells by SAMHD1 limits virus-induced production of interferons and the induction of co-stimulatory markers
These data support a model in which SAMHD1 catalytic activity is regulated through tetramer stabilization by the carboxyl-terminal tail, phosphorylation destabilizing the complexes and inactivating the enzyme. ISF2 may serve to reduce the dNTP pool to very low levels as a means of restricting virus replication.
These observations suggest that heterozygous cancer-associated SAMHD1 mutations increase mutation rates in cancer cells.
SAMHD1 in the mouse blocks retroviral infection at the level of reverse transcription and is regulated through cell cycle-dependent phosphorylation.
phosphorylation of mSAMHD1 at T634 by CDK1 (show CDK1 Proteins)/2 negatively regulates its HIV-1 restriction in differentiated cells, but does not affect its murine leukemia virus restriction in dividing cells.
SAMHD1 restricts HIV-1 replication and regulates interferon (show IFNA Proteins) production in mouse myeloid cells.
Allosteric regulation by dATP and dTTP works similarly in human and mouse SAMHD1.
SAMHD1 decreases dNTP pool in murine cells, restricts retroviral replication and regulates type I IFN production.
SAMHD1 can restrict lentiviruses in vivo and that nucleotide starvation is an evolutionarily conserved antiviral mechanism.
there are several Vpx residues required for SAMHD1 degradation
This gene may play a role in regulation of the innate immune response. The encoded protein is upregulated in response to viral infection and may be involved in mediation of tumor necrosis factor-alpha proinflammatory responses. Mutations in this gene have been associated with Aicardi-Goutieres syndrome.
