Swiss-port # Q13535 Human Serine/threonine-protein kinase ATR |
|---|---|
| Gene Symbol | ATR |
| Gene Full Name | ATR serine/threonine kinase |
| Background | The protein encoded by this gene is a serine/threonine kinase and DNA damage sensor, activating cell cycle checkpoint signaling upon DNA stress. The encoded protein can phosphorylate and activate several proteins involved in the inhibition of DNA replication and mitosis, and can promote DNA repair, recombination, and apoptosis. This protein is also important for fragile site stability and centrosome duplication. Defects in this gene are a cause of Seckel syndrome 1. [provided by RefSeq, Aug 2017] |
| Function | Serine/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. [UniProt] |
| Cellular Localization | Nucleus. Nucleus, PML body. Chromosome. Note=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. [UniProt] |
| Calculated MW | 301 kDa |
| PTM | Phosphorylated; autophosphorylates in vitro. [UniProt] |

Western blot: NIH/3T3 cells were treated by Nocodazole (50 ng/ml, 37°C, 20 hours) (left lane). NIH/3T3 cells were treated by UV (RT, 15-30 min) (middle lane). Untreated NIH/3T3 cells (right lane). 25 µg of cell lysates were stained with ARG43224 anti-ATR phospho (Ser428) antibody at 1:1000 dilution.
