The SMYD2 protein is a multifunctional methyltransferase that can modify histones and non-histone proteins, including p53/TP53 and RB1. Notably, it trimethylates H3 at "Lys-4" (H3K4me3), which is critical for gene activation. SMYD2 Protein, Human (sf9, His) is the recombinant human-derived SMYD2 protein, expressed by Sf9 insect cells , with N-His labeled tag.
