Predicted to contribute to histone acetyltransferase activity. Predicted to be involved in histone acetylation and regulation of transcription, DNA-templated. Predicted to act upstream of or within negative regulation of gene expression, epigenetic; positive regulation of striated muscle cell differentiation; and regulation of transcription by RNA polymerase II. Predicted to be located in nuclear membrane and nucleoplasm. Predicted to be part of Piccolo NuA4 histone acetyltransferase complex. Is expressed in several structures, including blood vessel endothelium; brain; heart; retina; and skeletal muscle. Orthologous to human EPC1 (enhancer of polycomb homolog 1).
