Application

DS-437 has been used as an inhibitor of protein arginine methyltransferase 5 (PRMT5) to study its effect on forkhead box P3 (FOXP3) methylation and regulatory T cells (Tregs) function in 293T cells.

Biochem/physiol Actions

DS-437 inhibits regulatory T cells (Tregs) function and methylation of forkhead box P3 (FOXP3) in 293T cells. DS-437 in combination with anti-p185erbB2/neu antibody 4D5 reduces tumor growth in CT26HER2 tumor-bearing mice.
DS-437 is an analog of S-adenosyl methionine (SAM ), which inhibits protein arginine methyltransferases PRMT5 and PRMT7 (IC50 5.9 and 6 μM) with little interaction against a panel of 30 other human methyltransferases.

Regulatory T cells (Tregs) are a subpopulation of T cells that are specialized in suppressing immune responses. Here we show that the arginine methyl transferase protein PRMT5 can complex with FOXP3 transcription factors in Tregs. Mice with conditional knock out
