  • Application notes
    Is unsuitable for IP.
  • Target

    • 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.

      Lane 2: SAMHD knockout HAP1 cell lysate (20 µg)
      Lane 3: K562 cell lysate (20 µg)
      Lanes 1 - 3: Merged signal (red and green). Green - ab177462 observed at 70 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab177462 was shown to recognize SAMHD1 when SAMHD1 knockout samples were used, along with additional cross-reactive bands. Wild-type and SAMHD1 knockout samples were subjected to SDS-PAGE. ab177462 and ab8245 (loading control to GAPDH) were both diluted 1/10000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
