Research Abstract |
Necdin interacted with Sirt1, which deacetylates various energy metabolism-associated proteins, and controlled the acetylation levels of the Fox01 transcription factor and neuropeptidergic neuron activities in the hypothalamus. Necdin also interacted with several elements of the SMC5/ 6 complex, which is involved in DNA repair, and enhanced its activity after DNA damage in postmitotic neurons. These results suggest that necdin serves as a hub protein in the protein interaction networks that are involved in energy metabolism and DNA repair to promote neuronal survival.
