Predicted to enable ATP binding activity; metal ion binding activity; and protein kinase activity. Predicted to be involved in several processes, including intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator; negative regulation of calcineurin-NFAT signaling cascade; and protein phosphorylation. Predicted to act upstream of or within peptidyl-tyrosine phosphorylation. Part of ribonucleoprotein complex. Is expressed in several structures, including brain; eye; gut gland; hemolymphoid system gland; and reproductive system. Orthologous to human DYRK2 (dual specificity tyrosine phosphorylation regulated kinase 2). [provided by Alliance of Genome Resources, Apr 2022]
