Abstract
  • Menin, the nuclear protein encoded by the Multiple Endocrine Neoplasia type 1 (MEN1) gene, acts as a tumor suppressor. It interacts with a large number of proteins involved in chromatin modification, transcription, cell cycle checkpoint and DNA repair, though its exact function is not clear. We report that in human cells menin stimulates homology-directed (HD) DNA repair induced by the rare endonuclease I-SceI and it accumulates with Chk1 at the site of the double strand break. In addition, menin and Chk1 interact in vivo. Deletion of the first 228 amino acids of menin impairs the interaction with Chk1 and the ability to stimulate HD repair, suggesting that the complex menin-Chk1 on the damaged chromatin facilitates homologous recombination.
