CC -!- FUNCTION: Sequence-specific DNA-binding transcription factor (By
CC similarity). Plays a role in hindbrain segmentation by regulating the
CC expression of a subset of homeobox containing genes and in Schwann cell
CC myelination by regulating the expression of genes involved in the
CC formation and maintenance of myelin (By similarity). Binds to two EGR2-
CC consensus sites EGR2A (5'-CTGTAGGAG-3') and EGR2B (5'-ATGTAGGTG-3') in
CC the HOXB3 enhancer and promotes HOXB3 transcriptional activation (By
CC similarity). Binds to specific DNA sites located in the promoter region
CC of HOXA4, HOXB2 and ERBB2 (By similarity). Regulates hindbrain
CC segmentation by controlling the expression of Hox genes, such as HOXA4,
CC HOXB3 and HOXB2, and thereby specifying odd and even rhombomeres (By
CC similarity). Promotes the expression of HOXB3 in the rhombomere r5 in
CC the hindbrain (By similarity). Regulates myelination in the peripheral
CC nervous system after birth, possibly by regulating the expression of
CC myelin proteins, such as MPZ, and by promoting the differentiation of
CC Schwann cells (By similarity). Involved in the development of the jaw
CC openener musculature, probably by playing a role in its innervation
CC through trigeminal motor neurons (By similarity). May play a role in
CC adipogenesis, possibly by regulating the expression of CEBPB (By
CC similarity). {ECO:0000250|UniProtKB:P08152}.
CC -!- FUNCTION: E3 SUMO-protein ligase helping SUMO1 conjugation to its
CC coregulators NAB1 and NAB2, whose sumoylation down-regulates EGR2
CC transcriptional activity. {ECO:0000250|UniProtKB:P11161}.
CC -!- PATHWAY: Protein modification; protein sumoylation.
CC -!- SUBUNIT: Interacts with HCFC1 (By similarity). Interacts with WWP2 (By
CC similarity). Interacts with UBC9 (By similarity). Interacts with CITED1
CC (By similarity). Interacts (via phosphorylated form) with SFN (By
CC similarity). {ECO:0000250|UniProtKB:P08152,
CC ECO:0000250|UniProtKB:P11161}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P08152}.
CC -!- PTM: Ubiquitinated by WWP2 leading to proteasomal degradation.
CC {ECO:0000250|UniProtKB:P08152}.
CC -!- PTM: Acetylated. May be deacetylated by HDAC6, HDAC10 or SIRT1.
CC {ECO:0000250|UniProtKB:P08152}.
CC -!- SIMILARITY: Belongs to the EGR C2H2-type zinc-finger protein family.
CC {ECO:0000305}.
