CIITA is the transcriptional activator for MHC class II and related genes. Its predominantly found in the nucleus by action of an NLS but can also be found in the cytoplasm, as the localization of the protein is regulated by various post-translational modifications. Raval et al. found that GTP-binding domain (421-561) negatively regulates export and CRM1 binding (tested by co-IP with cellular lysates). Voong et al. found that inhibition of ERK1/2 phosphorylation of CIITA causes nuclear accumulation and that CRM1 binds preferably to the phosphorylated from in co-IP experiment with lysates. Most recently, Chiu et al. performed truncation analysis and isolated fragment 612-764 to have NES activity, where peptide comprising of 717-724 is sufficient to have LMB-sensitive export activity. L720 and L724 mutations in the context of full length protein rendered the localization not responsive to LMB and accumulates in the nucleus. However no effect was observed for L717A and L722A. This suggest that this NES does not follow traditional consensus and may have non-typical consensus like X11L2 NES.

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.
