Description

Definition and Core Characteristics

MEF2D antibodies are polyclonal or monoclonal immunoglobulin preparations that specifically bind to the MEF2D protein, a member of the MEF2 family of transcription factors. Key features include:

  • Host species: Primarily rabbit-derived IgG antibodies

  • Target specificity: Recognizes human, mouse, and other species' MEF2D isoforms

  • Molecular weight: Detects endogenous MEF2D at ~70 kDa

Key Applications in Research

These antibodies serve multiple experimental roles across biological disciplines:

Transcriptional Regulation Mechanisms

ChIP-chip analyses using MEF2D antibodies identified 182 direct target genes involved in:

  • Neuronal survival pathways

  • Synaptic plasticity regulation

  • Stress response systems

Control experiments demonstrated antibody specificity through peptide antigen preabsorption, eliminating false positives in promoter binding assays .

Oncological Implications

Recent breast cancer studies revealed:

These findings position MEF2D as a tumor suppressor through its regulation of:

  • Cell cycle progression checkpoints

Disease Relevance and Therapeutic Potential

Emerging evidence demonstrates MEF2D's involvement in:

  • Neurological disorders: Regulates survival genes in Parkinson's disease models

  • Oncogenesis: Loss correlates with:

    • Increased mammary tumor incidence (78% in knockout models)

    • Enhanced metastatic potential through TWIST1 upregulation

Target Background

Function
MEF2D Antibody is a transcriptional activator that binds specifically to the MEF2 element, 5'-YTA[AT](4)TAR-3', which is found in numerous muscle-specific, growth factor- and stress-induced genes. It mediates cellular functions not only in skeletal and cardiac muscle development, but also in neuronal differentiation and survival. MEF2D plays diverse roles in the control of cell growth, survival and apoptosis via p38 MAPK signaling in muscle-specific and/or growth factor-related transcription. It plays a critical role in the regulation of neuronal apoptosis.
