ATM roles in different species
| Eukaryotes | ATM like gene | Function | Reference |
| Arabidopsis | ATM ortholog | DNA damage response via SOG1 phosphorylation | 33 |
| Saccharomyces cerevisiae | Tel 1 | Telomere length, DNA damage response | 34,35 |
| Caenorhabditis elegans | ATM-1 | DNA damage response (lacking the large N-terminal region present in other ATM homologs) | 36 |
| Aspergillus nidulans | AtmA | DNA damage response and polarized hyphal growth (formation of a stable axis of hyphal polarity) | 37 |
| Zebrafish | zATM | DNA damage response (67% and 66% homology with human ATM and mouse ATM) | 38 |
| Drosophila | dATM | DNA damage response and eye and wing development | 39 |
| Mouse and mice | DNA damage response, embryonic development, infertility, neurological function | 40-43 |
