Enables beta-catenin binding activity and histone-arginine N-methyltransferase activity. Involved in several processes, including histone methylation; negative regulation of G1/S transition of mitotic cell cycle; and regulation of transcription, DNA-templated. Predicted to be located in cytosol and nucleoplasm. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human PRMT2 (protein arginine methyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
