    basic FUNCTION
  • associating with HDAC4, HDAC in regulation of skeletal myogenesis, cardiac morphogenesis and right ventricular development and important regulator of chondrocyte gene expression
  • may be having a fundamental role in ventricular cardiomyocyte differentiation and apportioning of cells between inflow and outflow precursors in the primary heart field
  • important component in GNA13-mediated angiogenesis
  • mediating calcium-dependent transcription of the interleukin-2 gene in T lymphocytes
  • implicated in neuronal activity-dependent cell survival, and may be regulate excitatory synapse number and postsynaptic differentiation of dendrites
  • required to limit excessive increases in the number of excitatory synapses, although it does not hinder synaptogenesis seen during initial development of synaptic connectivity
  • facilitates learning and memory by negative regulation of synapse numbers and function
  • playing a crucial role in programming early neuronal differentiation and proper distribution within the layers of the neocortex
  • implicated in the regulation of adult bone mass
  • plays a pivotal role in early neuronal differentiation
  • functional cooperation of TBX5 and MEF2C links MEF2C to the higher-order protein complex regulating heart development
  • important regulator of brain, skeleton, lymphocyte and cardiovascular development and is required in the neural crest for craniofacial development
  • might serve as a potentiator of the transcriptional pathways affected in Waardenburg syndromes
  • is a transcriptional regulator of homeostasis in rod photoreceptor cells
  • GLI2 and MEF2C play important roles in the development of embryonic heart muscle and enhance cardiomyogenesis in stem cells
  • key role of MEF2C isoform in the brain, suggesting that MEF2A and MEF2D have only subtle roles in regulating hippocampal synaptic function (
  • novel role for MEF2C/MEF2D in coordinating the transcriptional network that promotes early B-cell development
  • CELLULAR PROCESS nucleotide, transcription, regulation

    PATHWAY
    metabolism
    signaling
    a component
  • the MEF2C-SOST transcriptional axis has important implications for the anabolic treatment of disorders in which bone loss is a significant component
  • INTERACTION
    DNA binding to myocyte-specific enhancer
    RNA
    small molecule
    protein
  • binding to TWIST to inhibit myogenesis
  • binding MITR, HDAC4
  • binding to members of the MyoD family of transcriptional activator
  • interacting with NFATC2
  • binding SUV39H1 and CABIN1 (targeting its promoter in a calcium-dependent manner)
  • interacting with SMYD1 (SMYD1 expression in the developing heart depends on the direct binding of MEF2C to a MEF2-response element in the SMYD1 promoter)
  • physically associates with TBX5 and cooperatively activates transcription from the MYH6 promoter
  • PIN1 interacts selectively with phosphorylated MEF2C in skeletal muscle cells
  • direct transcriptional target of SOX10 and MEF2A via a evolutionarily conserved enhancer
  • MEF2C expression from an alternative promoter in the retina is regulated by NRL
  • MEF2C is the main transcription factor responsible for bone enhancer ECR5-dependent SOST transcriptional activation in the adult skeleton
  • POSTN regulates SOST expression upstream of MEF2C
  • APLN, APLNR signaling is a potent regulator of endothelial MEF2C function in the developing cardiovascular system
  • essential and redundant roles of MEF2A, MEF2C, and MEF2D in satellite cell differentiation
  • is positioned to interact with the MEF2C pathway known to be important in developmental epilepsies and the CREB1 pathway implicated in epilepsy pathogenesis
  • MEF2C regulates outflow tract alignment and transcriptional control of TDGF1

    ANIMAL & CELL MODELS
  • mice displayed autistic phenotypes resembling Rett syndrome in that they manifested altered anxiety and increased stereotypy (purposeless movements) on neurobehavioral testing, representing key characteristics of autism-spectrum disorders
  • inactivation of Mef2c in the neural crest of mice results in reduced expression of melanocyte genes during development and a significant loss of pigmentation at birth due to defective differentiation and reduced abundance of melanocytes
