Some NAC proteins are anchored in the plasma membrane or endoplasmic reticulum membrane (Liang et al., 2015). They are merged into transmembrane NAC protein subfamily named NTL (from NTM1-like). In response to abiotic stresses, their transport to the nucleus occurs after proteolytic cleavage (Seo et al., 2008). For example, MfNACsa (a lipid-anchored NACsa TF in Medicago falcata) is associated with membranes under unstressed conditions. Under drought stress, MfNACsa translocates to the nucleus through de-S-palmitoylation mediated by the thioesterase MtAPT1 (Wang et al., 2017a).

Forkhead box class O (FoxO) is a nuclear protein subfamily that mediates the inhibitory actions of insulin or insulin-like growth factor on key genes. In turn, these inhibitory actions affect cell cycle regulation, energy metabolism, proteostasis, oxidative stress, apoptosis, and immunity.[9] Among the 19 FoxO signaling genes observed in this study, 18, including FOXO3, SMAD3, SMAD4, INSR, PI3K, and G1/S-specific cyclin D2 (CCND2), were significantly upregulated in response to RET exposure. The exception was tumor necrosis factor ligand superfamily member 6 (FASL) (Figure 8 and Table A3). FOXO3 is a transcriptional activator.[60]In vivo, FOXO3 reportedly promotes hepatic triglyceride accumulation, impairs glucose tolerance, and contributes to the upregulation of numerous lipogenic genes, such as GPAM.[48] A similar result has been reported in Caenorhabditis elegans[61] that FOXO3 stimulates lipid accumulation, so the abnormal expression of FOXO3 may impact lipid metabolism.
