MAPK-activated protein kinase 2 (MK2) phosphorylates BRF1 at serine 54, serine 92, serine 203, and an unknown site in the C terminus. Phosphorylation inhibits the ability of BRF1 to cause degradation of RNA. It is unknown if tetraphosphorylated BRF1 binds 14-3-3 in the same way as diphosphorylated BRF1 does.
