Comments
MondoA belongs to the basic region helix-loop-helix leucine zipper (bHLHZip) family of transcription factors. MondoA localizes predominantly to the cytoplasm. Eliers et al. showed that the presence of either the N-terminal Mondo conserved regions (MCRs) or the conserved C-terminal region of MondoA is sufficient for the cytoplasmic localization of MondoA. The MCR II contains a functional NES, which is required for the cytoplasmic localization of the heterodimer of MondoA and Mlx. Apparently, the dimerizatiion abolishes the cytoplasmic localization activity of the C-terminus. The NES in MCRII is conserved in MondoB/chREBP and was shown to regulate the localization of chREBP by Sakiyama et al. MCR III of MondoA can interact with protein 14-3-3. MondoA (446-811) is localized to the nucleus, suggesting the existence of NLS.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
