Enables DNA-binding transcription factor activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Involved in several processes, including cellular response to calcium ion; cellular response to glucose stimulus; and dendrite morphogenesis. Located in nucleus. Human ortholog(s) of this gene implicated in dilated cardiomyopathy. Orthologous to human MEF2A (myocyte enhancer factor 2A). [provided by Alliance of Genome Resources, Apr 2022]
