The kinase DYRK1A phosphorylates the transcription factor FKHR at Ser329 in vitro, a novel in vivo phosphorylation siteApril 24, 2001Synopsis: Two papers from Woods and colleagues describe novel roles for members of the dual specificity tyrosine phosphorylated and regulated kinase (DYRK) family. In one, DYRK1A is shown to phosphorylate a novel site in the transcription factor FKHR (a forkhead protein) regulating its nuclear presence and transcriptional activity. In the second paper, it is shown that both DYRK1A and DYRK2 can phosphorylate sites on eIF2BE and Tau that are required for priming phosphorylation by GSK-3. These observations have implications not only with respect to mapping insulin, and related growth factor control pathways, but also in providing a basis for understanding genetics aberrations associated with the DYRK1A region of chromosome 21.
