Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and histone deacetylase binding activity. Acts upstream of or within positive regulation of transcription by RNA polymerase II. Predicted to be located in cell junction; cytosol; and nucleoplasm. Predicted to be part of transcription regulator complex. Is expressed in several structures, including central nervous system; embryo mesenchyme; heart; musculature; and urinary system. Orthologous to several human genes including MEF2B (myocyte enhancer factor 2B). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

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.

Whereas MEF2A is absolutely required for proper myoblast differentiation, MEF2B, -C, and -D were found to be dispensable for this process.

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.
