Crosstalk between Arg296/Arg299 methylation and Ser302 phosphorylation results in role switch of hnRNPK in DNA damage response. Frequently occurred methylation of Arg296/Arg299 suppresses the PKCδ-mediated Ser302 phosphorylation, which results in the anti-apoptotic effect of hnRNPK. Alternatively, low level of Arg296/Arg299 methylation promotes the nearby Ser302 phosphorylation and pro-apoptotic effect of hnRNPK after DNA damage.
