Dual specificity tyrosine-phosphorylation-regulated kinase 2 is anenzyme, in particular adual-specificity kinase, that in humans is encoded by theDYRK2gene.[5][6]
DYRK2 belongs to a family of proteinkinases whose members are presumed to be involved in cellular growth and development. The family is defined by structural similarity of their kinase domains and their capability toautophosphorylate on tyrosine residues. DYRK2 has demonstrated tyrosine autophosphorylation and catalyzed phosphorylation ofhistones H3 and H2B in vitro. Twoisoforms of DYRK2 have been isolated. The predominant isoform, isoform 1, lacks a 5' terminal insert.[6]
