Summary: The product of this gene is a member of the MADS/MEF2 family of DNA binding proteins. The protein is thought to regulate gene expression, including expression of the smooth muscle myosin heavy chain gene. This region undergoes considerable alternative splicing, with transcripts supporting two non-overlapping loci (GeneID 729991 and 100271849) as well as numerous read-through transcripts that span both loci (annotated as GeneID 4207). Several isoforms of this protein are expressed from either this locus or from some of the read-through transcripts annotated on GeneID 4207. [provided by RefSeq, Jan 2014]

Studied expression of myocyte enhancer factor 2B (MEF2B) as part of the diffuse large (DLBCL) B-cell lymphoma 6 (BCL6) transcription complex in diffuse large B-cell lymphoma tissue samples and cell lines. Findings indicate MEF2B to be an essential component of the BCL6 gene transcriptional complex for the regulation of DLBCL growth thru promotion of BCL6 expression.

Mef2b deletion reduces germinal center (GC) formation in mice and identify MEF2B transcriptional targets in GC, with roles in cell proliferation, apoptosis, GC confinement, and differentiation. The most common lymphoma-associated MEF2B mutant (MEF2BD83V) is hypomorphic yet escapes binding and negative regulation by components of the HUCA complex and class IIa HDACs.
Title: MEF2B Instructs Germinal Center Development and Acts as an Oncogene in B Cell Lymphomagenesis.
Although the mechanisms by which the D83V mutation in MEF2B promote oncogenesis in lymphoma cells remain to be elucidated, the observation that a mutation hotspot coincides with a conformation switch site on MEF2B reflects a remarkable convergence of tumor growth selection pressure and the physical/ chemical forces behind protein folding.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
