Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including anterior midgut development; carbohydrate storage; and positive regulation of macromolecule metabolic process. Located in nucleus. Is expressed in several structures, including adult brain; circulatory system; dorsal vessel primordium; extended germ band embryo; and muscle cell. Human ortholog(s) of this gene implicated in autosomal dominant mental retardation 20 and dilated cardiomyopathy. Orthologous to several human genes including MEF2C (myocyte enhancer factor 2C).

SIK3 promotes the cytosolic localization of HDAC4, thereby relieving inhibition of Mef2-dependent transcription of K(+) and water transport molecules

Ethanol activates the Mef2. Reduced Mef2 activity in all neurons or specifically in the mushroom body decreases ethanol tolerance.
Title: Mef2 induction of the immediate early gene Hr38/Nr4a is terminated by Sirt1 to promote ethanol tolerance.
The authors show that loss of frataxin homolog (fh) in Drosophila leads to iron toxicity, which in turn induces sphingolipid synthesis and ectopically activates 3-phosphoinositide dependent protein kinase-1 (Pdk1) and myocyte enhancer factor-2 (Mef2).
Title: Loss of Frataxin induces iron toxicity, sphingolipid synthesis, and Pdk1/Mef2 activation, leading to neurodegeneration.
CF2 expression variations yield altered Mef2 expression levels but with correct spatio-temporal Mef2 expression patterns, it can be concluded that only the mechanism controlling expression levels is de-regulated. Here, it is proposed that CF2 regulates Mef2 expression through a Feedforward Loop circuit.
Title: CF2 transcription factor is involved in the regulation of Mef2 RNA levels, nuclei number and muscle fiber size.
Overexpression of Tinman and Pannier resulted in 20% of embryos with ectopic Hand and Sur expression. By adding MEF2 alongside Tinman and Pannier, an expansion in expression of Hand and Sur was observed.

Our results show that Mef2 and possibly Sd regulate a Dl enhancer specifically expressed in the developing indirect flight muscles and that Mef2 is required for Dl expression in developing indirect flight muscles.
