The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder.

Western blotting analysis using ATM antibody . Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with ATM antibody and HRP-conjugated goat anti-rabbit secondary antibody respectively. Image was developed using FeQ™ ECL Substrate Kit .

Western blotting analysis using ATM antibody . ATM expression in wild type (WT) and ATM knockdown (KD) 293T cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with ATM antibody and HRP-conjugated goat anti-rabbit secondary antibody respectively. Image was developed using FeQ™ ECL Substrate Kit .

Flow cytometric analysis of ATM expression in HepG2 cells using ATM antibody . Green, isotype control; red, ATM.

Immunocytochemical staining of HepG2 cells with ATM antibody . Nuclei were stained blue with DAPI; ATM was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: Medium. Scale bar, 20 μm.
