a dual-specificity protein kinase of the DYRK family. Localizes in the cytoplasm. Phosphorylates the translation initiation factor eIF2B at Ser539, priming it for phosphorylation by glycogen synthase kinase-3. Note: This description may include information from UniProtKB.
Protein type: Protein kinase, CMGC; Protein kinase, dual-specificity (non-receptor); Kinase, protein; EC 18.104.22.168; CMGC group; DYRK family; Dyrk2 subfamily
Molecular Function: ATP binding; magnesium ion binding; manganese ion binding; protein binding; protein serine/threonine kinase activity; protein serine/threonine/tyrosine kinase activity; protein-tyrosine kinase activity; ubiquitin binding
Biological Process: DNA damage response, signal transduction by p53 class mediator resulting in induction of apoptosis; negative regulation of NFAT protein import into nucleus; peptidyl-tyrosine phosphorylation; positive regulation of glycogen biosynthetic process; protein amino acid phosphorylation; response to DNA damage stimulus; smoothened signaling pathway
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
