| 亚基 | 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 KMT2D/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). |
| 亚细胞定位 | Nucleus |
| 组织特异性 | Expressed in hematopoietic cells and also in colon and testis. |
| 翻译后修饰 | Phosphorylated on serine residues. In undifferentiated erythrocytes, phosphorylated by MAPK8 which then leads to ubiquitination and protein degradation. Sumoylated. Sumoylation is required for translocation to nuclear bodies PODs, anchoring to the gene loci, and transactivation of the beta-globin gene. 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). |
| 相似性 | Belongs to the bZIP family. CNC subfamily. |
| 功能 | 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. |
