ID:NFE2_HUMAN DESCRIPTION: RecName: Full=Transcription factor NF-E2 45 kDa subunit; AltName: Full=Leucine zipper protein NF-E2; AltName: Full=Nuclear factor, erythroid-derived 2 45 kDa subunit; AltName: Full=p45 NF-E2; FUNCTION: Component of the NF-E2 complex essential for regulating erythroid and megakaryocytic maturation and differentiation. Binds to the hypersensitive site 2 (HS2) of the beta-globin control region (LCR). This subunit (NFE2) recognizes the TCAT/C sequence of the AP-1-like core palindrome present in a number of erythroid and megakaryocytic gene promoters. Requires MAFK or other small MAF proteins for binding to the NF-E2 motif. May play a role in all aspects of hemoglobin production from globin and heme synthesis to procurement of iron. SUBUNIT: Homodimer; can bind DNA as a homodimer. Erythroid transcription activator nuclear factor erythroid-derived 2 (NF- E2), composed of a heterodimer of NFE2 and MAFK, possesses transactivation activity on beta-globin. Also forms high affinity heterodimer with MAFG; the interaction promotes erythropoiesis. Interacts (via the PXY motif 1) with ITCH (via the WW 1 domain); the interaction promotes 'Lys63'-linked ubiquitination of NFE2, translocates it to the cytoplasm and inhibits its transactivation activity. Interacts with MLL2; the interaction promotes transactivation of the beta-globin locus (By similarity). Interacts with MAPK8 (phosphorylated form); the interaction leads to phosphorylation of NFE2 in undifferentiated cells (By similarity). SUBCELLULAR LOCATION: Nucleus, PML body. Cytoplasm. Note=The sumoylated form locates to the nuclear bodies PML oncogenic domains (PODs). Translocated to the cytoplasm through interaction with ITCH. TISSUE SPECIFICITY: Expressed in hematopoietic cells and also in colon and testis. DOMAIN: The PXY motifs are required for binding WW domains. PXY1 is required to promote transactivation of beta-globin and for hyperacetylation of histone H3, but not for binding to the HS2 promoter site (By similarity). PTM: Phosphorylated on serine residues (By similarity). In undifferentiated erythrocytes, phosphorylated by MAPK8 which then leads to ubiquitination and protein degradation (By similarity). PTM: Sumoylated. Sumoylation is required for translocation to nuclear bodies PODs, anchoring to the gene loci, and transactivation of the beta-globin gene. PTM: Ubiquitinated mainly by 'Lys63'-linked ubiquitin. Polyubiquitination with 'Lys63'-linked ubiquitin by ITCH retains NFE2 in the cytoplasm preventing its transactivation activity. In undifferentiated erythrocyte, ubiquitinated after MAPK8-mediatd phosphorylation leading to protein degradation (By similarity). SIMILARITY: Belongs to the bZIP family. CNC subfamily. SIMILARITY: Contains 1 bZIP (basic-leucine zipper) domain. WEB RESOURCE: Name=SeattleSNPs; URL="http://pga.gs.washington.edu/data/nfe2/";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
