• Immunogen: A synthesized peptide derived from human MEF2C around the phosphorylation site of Ser222.
• Conjugation: Unconjugated

• Post Translational Modifications: Phosphorylation on Ser-59 enhances DNA binding activity (By similarity). Phosphorylation on Ser-396 is required for Lys-391 sumoylation and inhibits transcriptional activity. Acetylated by p300 on several sites in diffentiating myocytes. Acetylation on Lys-4 increases DNA binding and transactivation (By similarity). Sumoylated on Lys-391 with SUMO2 but not by SUMO1 represses transcriptional activity.Proteolytically cleaved in cerebellar granule neurons, probably by caspase 7, following neurotoxicity. Preferentially cleaves the CDK5-mediated hyperphosphorylated form which leads to neuron apoptosis and transcriptional inactivation.
• Subunit Structure: Forms a complex with class II HDACs in undifferentiating cells. On myogenic differentiation, HDACs are released into the cytoplasm allowing MEF2s to interact with other proteins for activation. Interacts with EP300 in differentiating cells; the interaction acetylates MEF2C leading to increased DNA binding and activation (By similarity). Interacts with HDAC7 and CARM1 (By similarity). Interacts with HDAC4 and HDAC9; the interaction with HDACs represses transcriptional activity. Interacts with LPIN1. Interacts with MYOCD. Interacts with AKAP13 (By similarity). Interacts with FOXK1; the interaction inhibits MEF2C transactivation activity (By similarity). Interacts (via N-terminus) with HABP4; this interaction decreases DNA-binding activity of MEF2C in myocardial cells in response to mechanical stress. Interacts with JPH2; interaction specifically takes place with the Junctophilin-2 N-terminal fragment cleavage product of JPH2 (By similarity). Interacts (via MADS box) with SOX18 (By similarity).
• Similarity: The beta domain, missing in a number of isoforms, is required for enhancement of transcriptional activity.Belongs to the MEF2 family.
• Subcellular Location: Nucleus. Cytoplasm>Sarcoplasm.
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Immunohistochemistry (IHC)

(At 1/100 staining Mouse brain tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the primary antibody at 4 degree C overnight. An HRP conjugated anti-Rabbit antibody was used as the secondary antibody.)

Related Product Information for anti-MEF2C antibody

Transcription activator which binds specifically to the MEF2 element present in the regulatory regions of many muscle-specific genes. Controls cardiac morphogenesis and myogenesis, and is also involved in vascular development. Enhances transcriptional activation mediated by SOX18. Plays an essential role in hippocampal-dependent learning and memory by suppressing the number of excitatory synapses and thus regulating basal and evoked synaptic transmission. Crucial for normal neuronal development, distribution, and electrical activity in the neocortex. Necessary for proper development of megakaryocytes and platelets and for bone marrow B-lymphopoiesis. Required for B-cell survival and proliferation in response to BCR stimulation, efficient IgG1 antibody responses to T-cell-dependent antigens and for normal induction of germinal center B-cells. May also be involved in neurogenesis and in the development of cortical architecture (By similarity). Isoforms that lack the repressor domain are more active than isoform 1.

NCBI Description

This locus encodes a member of the MADS box transcription enhancer factor 2 (MEF2) family of proteins, which play a role in myogenesis. The encoded protein, MEF2 polypeptide C, has both trans-activating and DNA binding activities. This protein may play a role in maintaining the differentiated state of muscle cells. Mutations and deletions at this locus have been associated with severe mental retardation, stereotypic movements, epilepsy, and cerebral malformation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2010]
