  • Function

    Putative nuclease involved in innate immune response by acting as a negative regulator of the cell-intrinsic antiviral response. May play a role in mediating proinflammatory responses to TNF-alpha signaling.
  • Tissue specificity

    Expressed in heart, skeletal muscle, spleen, liver, small intestine, placenta, lung and peripheral blood leukocytes. No expression is seen in brain and thymus.
  • Involvement in disease

    Defects in SAMHD1 are the cause of Aicardi-Goutieres syndrome type 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.
  • Sequence similarities

    Belongs to the SAMHD1 family.
    Contains 1 HD domain.
    Contains 1 SAM (sterile alpha motif) domain.

  • Immunofluorescence analysis of HeLa cells expressing SAMHD1 fused to murine NIH3T3 (3T3) cells, staining SAMHD1 with ab67820. HeLa cells expressing the SAMHD1 were fused to murine NIH3T3 cells with PEG to induce heterokaryon formation. Cells were fixed with 4% formalin, permeabilized with 0.5% Triton X-100 before incubating with primary antibody

Thank you for contacting Abcam Technical Team and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this product. All our customer feedback, including complaints are monitored weekly by our in house technical support team. If a product is at fault the technical support team will consider removing the product from our catalogue in order to avoid future customer inconvenience. This is a very first complaint about this antibody so we are not aware of any quality-related issues. I appreciate very much that you have attached the WB results to this e-mail and provided some further details of the experiments. It is very clear to me that the two batches (GR19443-2 and GR52366-1) performed differently. At this stage, I am unable to identify the source of this problem but the two batches represent two different purifications. As our Abpromise applies to this complaint, this is to confirm that I have placed a new order for you for one vial of ab67820 (different batch: 1155439) as a free of charge replacement. I hope the second vial will work as it is expected, and please do let me know how you are getting on with this product.
