CC -!- FUNCTION: Component of the NF-E2 complex essential for regulating
CC erythroid and megakaryocytic maturation and differentiation. Binds to
CC the hypersensitive site 2 (HS2) of the beta-globin control region
CC (LCR). This subunit (NFE2) recognizes the TCAT/C sequence of the AP-1-
CC like core palindrome present in a number of erythroid and
CC megakaryocytic gene promoters. Requires MAFK or other small MAF
CC proteins for binding to the NF-E2 motif. May play a role in all aspects
CC of hemoglobin production from globin and heme synthesis to procurement
CC of iron (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer; can bind DNA as a homodimer (By similarity).
CC Erythroid transcription activator nuclear factor erythroid-derived 2
CC (NF-E2), composed of a heterodimer of NFE2 and MAFK, possesses
CC transactivation activity on beta-globin. Also forms high affinity
CC heterodimer with MAFG; the interaction promotes erythropoiesis.
CC Interacts (via the PXY motif 1) with ITCH (via the WW 1 domain); the
CC interaction promotes 'Lys63'-linked ubiquitination of NFE2,
CC translocates it to the cytoplasm and inhibits its transactivation
CC activity. Interacts with KMT2D/MLL2; the interaction promotes
CC transactivation of the beta-globin locus. Interacts with MAPK8
CC (phosphorylated form); the interaction leads to phosphorylation of NFE2
CC in undifferentiated cells (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus, PML body {ECO:0000250}. Cytoplasm
CC {ECO:0000250}. Note=The sumoylated form locates to the nuclear bodies
CC PML oncogenic domains (PODs). Translocated to the cytoplasm through
CC interaction with ITCH. {ECO:0000250}.
CC -!- DOMAIN: The PXY motifs are required for binding WW domains. PXY1 is
CC required to promote transactivation of beta-globin and for
CC hyperacetylation of histone H3, but not for binding to the HS2 promoter
CC site. {ECO:0000250}.
CC -!- PTM: Phosphorylated on serine residues. In undifferentiated
CC erythrocytes, phosphorylated by MAPK8 which then leads to
CC ubiquitination and protein degradation. {ECO:0000250}.
CC -!- PTM: Sumoylated. Sumoylation is required for translocation to nuclear
CC bodies PODs, anchoring to the gene loci, and transactivation of the
CC beta-globin gene. {ECO:0000250}.
CC -!- PTM: Ubiquitinated mainly by 'Lys63'-linked ubiquitin.
CC Polyubiquitination with 'Lys63'-linked ubiquitin by ITCH retains NFE2
CC in the cytoplasm preventing its transactivation activity. In
CC undifferentiated erythrocyte, ubiquitinated after MAPK8-mediatd
CC phosphorylation leading to protein degradation. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the bZIP family. CNC subfamily. {ECO:0000305}.
