CC -!- FUNCTION: Transcriptional regulator which can act as both a
CC transcriptional repressor and activator by binding a DNA sequence on
CC these target genes and is involved in processes like cell
CC differentiation, cell migration and cell survival. Transactivates gene
CC expression by binding a 5'-[CAT]A[CT][CT][CTG]GA[GAT]-3' motif present
CC in the Trex site and a 5'-TCA[AG][AG]TTNC-3' motif present in the MEF3
CC site of the muscle-specific genes enhancer. Acts cooperatively with EYA
CC proteins to transactivate their target genes through interaction and
CC nuclear translocation of EYA protein. Acts synergistically with SIX1 to
CC regulate target genes involved in formation of various organs,
CC including muscle, kidney, gonad, ganglia, olfactory epithelium and
CC cranial skeleton. Plays a role in several important steps of muscle
CC development. Controls the genesis of hypaxial myogenic progenitors in
CC the dermomyotome by transactivating PAX3 and the delamination and
CC migration of the hypaxial precursors from the ventral lip to the limb
CC buds through the transactivation of PAX3, MET and LBX1. Controls
CC myoblast determination by transactivating MYF5, MYOD1 and MYF6.
CC Controls somitic differentiation in myocyte through MYOG
CC transactivation. Plays a role in synaptogenesis and sarcomere
CC organization by participating in myofiber specialization during
CC embryogenesis by activating fast muscle program in the primary myotome
CC resulting in an up-regulation of fast muscle genes, including ATP2A1,
CC MYL1 and TNNT3. Simultaneously, is also able to activate inhibitors of
CC slow muscle genes, such as SOX6, HRASLS, and HDAC4, thereby restricting
CC the activation of the slow muscle genes. During muscle regeneration,
CC negatively regulates differentiation of muscle satellite cells through
CC down-regulation of MYOG expression. During kidney development regulates
CC the early stages of metanephros development and ureteric bud formation
CC through regulation of GDNF, SALL1, PAX8 and PAX2 expression. Plays a
CC role in gonad development by regulating both testis determination and
CC size determination. In gonadal sex determination, transactivates ZFPM2
CC by binding a MEF3 consensus sequence, resulting in SRY up-regulation.
CC In gonadal size determination, transactivates NR5A1 by binding a MEF3
CC consensus sequence resulting in gonadal precursor cell formation
CC regulation. During olfactory development mediates the specification and
CC patterning of olfactory placode through fibroblast growth factor and
CC BMP4 signaling pathways and also regulates epithelial cell
CC proliferation during placode formation. Promotes survival of sensory
CC neurons during early trigeminal gangliogenesis. In the developing
CC dorsal root ganglia, up-regulates SLC12A2 transcription. Regulates
CC early thymus/parathyroid organogenesis through regulation of GCM2 and
CC FOXN1 expression. Forms gustatory papillae during development of the
CC tongue. Also plays a role during embryonic cranial skeleton
CC morphogenesis. {ECO:0000250|UniProtKB:Q61321}.
