Summary: Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and histone deacetylase binding activity. Involved in several processes, including receptor guanylyl cyclase signaling pathway; regulation of acetylcholine secretion, neurotransmission; and regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including anal region; body wall; head; intestine; and odorsensory neurons. Used to study autism spectrum disorder and intellectual disability. Human ortholog(s) of this gene implicated in dilated cardiomyopathy and neurodevelopmental disorder with hypotonia, stereotypic hand movements, and impaired language. Orthologous to several human genes including MEF2A (myocyte enhancer factor 2A); MEF2C (myocyte enhancer factor 2C); and MEF2D (myocyte enhancer factor 2D).

What's a GeneRIF?

miR-1 regulates the muscle transcription factor MEF-2, which results in altered presynaptic acetylcholine secretion, suggesting that MEF-2 activity in muscles controls a retrograde signal.
