Predicted to enable 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. Predicted to be involved in cell differentiation and positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of transcription, DNA-templated. Located in nucleus. Orthologous to several human genes including MEF2B (myocyte enhancer factor 2B). [provided by Alliance of Genome Resources, Apr 2022]
