DYRK2, or dual specificity tyrosine-phosphorylation-regulated kinase 2, has a role in the regulation of cellular growth and/or development. In response to DNA damage, DYRK2 regulates p53 phosphorylation on Ser-46 to induce apoptosis. DYRK2 has been proposed to inactivate GYS1 by phosphorylation at Ser-641, and potentially a second phosphorylation site, thus regulating glycogen synthesis. DYRK2 also phosphorylates EIF2B5 at Ser-544, enabling its subsequent phosphorylation and inhibition by GSK3, and may play a more general role in the priming of GSK3 substrates.
