    SUBCELLULAR LOCALIZATION     intracellular
  • continuously shuttles to the cytoplasm
  • expression in the nucleus increases progressively during the course of differentiation while decreasing in glial cells
  • basic FUNCTION
  • mediating calcium-dependent transcription of the interleukin-2 gene in T lymphocytes
  • activating transcription via the MEF2 element present in the regulatory regions of many muscle-specific genes
  • may be involved in muscle-specific and/or growth factor-related transcription
  • DNA binding proteins activating transcription of genes involved in control of muscle cell differentiation, and signaling pathways that mediate response to mitogenic signals and survival of neurons and T-lymphocytes
  • implicated in neuronal activity-dependent cell survival, and may be regulate excitatory synapse number and postsynaptic differentiation of dendrites
  • regulate neuronal development by controlling synapse formation and supporting the survival of newly formed neurons
  • nuclear transcription factor known to promote neuronal survival
  • transcription factor required for neuronal survival, that continuously shuttle to the cytoplasm, interact with the chaperone Hsc70, and undergo degradation
  • possible dual roles of MEF2A and MEF2D in macrophages, as activators or as repressors of gene transcription
  • neuronal survival factor MEF2D is decreased in Parkinson disease, and this decrease is specifically associated with SNCA accumulation and aggregation
  • key role of MEF2C isoform in the brain, suggesting that MEF2A and MEF2D have only subtle roles in regulating hippocampal synaptic function (
  • essential and redundant roles of MEF2A, MEF2C, and MEF2D in satellite cell differentiation
  • MEF2D is essential for photoreceptor and bipolar cell gene expression, either independently or cooperatively with CRX
  • in the retina MEF2D binds to retina-specific enhancers and controls photoreceptor cell development
  • is a key transcriptional mediator of pathological remodeling in the adult heart downstream of various stress-promoting insults

    a component
  • MEF2A/MEF2D dimers strongly interact with HDAC1, and to a lesser extent with HDAC7 in macrophages, whereas low levels of MEF2A/MEF2D–HDAC1 complexes are found in undifferentiated cells or in monocytes
  • binding to myocyte-specific enhancer
  • binding specifically to the MEF2 element present in the regulatory regions of many muscle-specific genes
  • RNA

  • YWHAQ/14-3-3tau
  • fusion MEF2D/DAZAP1 and/or DAZAP1/MEF2D contribute to leukemogenesis by altering signaling pathways normally regulated by wild-type MEF2D and DAZAP1
  • binding SUV39H1 and CABIN1 (targeting its promoter in a calcium-dependent manner)
  • interacting with the chaperone Hsc70 and undergo degradation
  • expression of MYOG is regulated, at least in part, by the decreased glycosylation-dependent recruitment of MEF2D to the promoter region, and this is one of the negative regulatory mechanisms of skeletal myogenesis by O-GlcNAc glycosylation
  • ATM phosphorylates and activates the transcription factor myocyte enhancer factor 2D (MEF2D), which plays a critical role in promoting survival of cerebellar granule cells
  • MEF2D and ROCK2 are RBFOX2 splicing targets
  • direct and specific RBFOX1 and RBFOX2 binding to MEF2D pre-mRNA
  • MEF2D achieves specificity by cooperating with a retina-specific factor CRX, which recruits MEF2D away from canonical MEF2 binding sites
  • is a critical regulator of IL10 gene expression that negatively controls microglia inflammation response and prevents inflammation-mediated cytotoxicity
  • expression of PTEN, the primary negative regulator of PI3K/Akt, was significantly reduced in MEF2D-deficient cardiomyocytes and found to be a direct target gene of MEF2D
