Myocyte enhancer binding factor 2B (MEF2B) is a transcription factor part of the MEF2 gene family including MEF2A, MEF2C, and MEF2D.[2][3] However, MEF2B is distant from the other three branches of MEF2 genes as it lacks the protein-coding Holliday junction recognition protein C-terminal (HJURP_C) region in vertebrates.[4]

Functions

The MEF2 gene family is expressed in muscle-specific gene activation and maintenance during development.[4][5] MEF2B mRNA is present in skeletal, smooth, brain and heart muscles.[6] MEF2B is directly involved in smooth muscle myosin heavy chain (SMHC) gene regulation. Overexpression of MEF2B will activate the SMHC promoter in smooth muscle when it is bound to the A/T-rich element of the promoter.[6]

Interactions

MEF2B has been shown to interact with CABIN1.[7][8]

Clinical relevance

Recurrent mutations in this gene have been associated with cases of diffuse large B-cell lymphoma.[9][10] In its mutated form, MEF2B can lead to deregulation of the proto-oncogene BCL6 expression in diffuse large B-cell lymphomas (DLBCL).[11] Mutations of MEF2B enhance its transcriptional activity due to either a disruption with its corepressor CABIN1 or causing the gene to become insensitive to inhibitory signaling events.[11]
