Application Abreviews Notes
  • Application notesWB: 1/15000 - 1/30000. Detects a band of approximately 300 kDa (predicted molecular weight: 307 kDa).

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionSerine/threonine protein kinase which activates checkpoint signaling upon genotoxic stresses such as ionizing radiation (IR), ultraviolet light (UV), or DNA replication stalling, thereby acting as a DNA damage sensor. Recognizes the substrate consensus sequence [ST]-Q. Phosphorylates BRCA1, CHEK1, MCM2, RAD17, RPA2, SMC1 and p53/TP53, which collectively inhibit DNA replication and mitosis and promote DNA repair, recombination and apoptosis. Phosphorylates 'Ser-139' of histone variant H2AX/H2AFX at sites of DNA damage, thereby regulating DNA damage response mechanism. Required for FANCD2 ubiquitination. Critical for maintenance of fragile site stability and efficient regulation of centrosome duplication.
    • Tissue specificityUbiquitous, with highest expression in testis. Isoform 2 is found in pancreas, placenta and liver but not in heart, testis and ovary.
    • Involvement in diseaseDefects in ATR are a cause of Seckel syndrome type 1 (SCKL1) [MIM:210600]. SCKL1 is a rare autosomal recessive disorder characterized by growth retardation, microcephaly with mental retardation, and a characteristic 'bird-headed' facial appearance.
    • Sequence similaritiesBelongs to the PI3/PI4-kinase family. ATM subfamily.
      Contains 1 FAT domain.
      Contains 1 FATC domain.
      Contains 2 HEAT repeats.
      Contains 1 PI3K/PI4K domain.
    • Post-translational
      Phosphorylated; autophosphorylates in vitro.
    • Cellular localizationNucleus. Nucleus > PML body. Depending on the cell type, it can also be found in PML nuclear bodies. Recruited to chromatin during S-phase. Redistributes to discrete nuclear foci upon DNA damage, hypoxia or replication fork stalling.
