General Information | Comment | Organism |
---|---|---|
malfunction | DYRK1A depletion leads to reduced Ser2/Ser5 phosphorylation at its target promoters. The combination of the loss of RNAPII association to the target promoters together with the reduced CTD phosphorylation of the elongating RNAPII is responsible for the reduced expression of the target genes upon DYRK1A depletion | Homo sapiens |
metabolism | DYRK1A is a dosage-sensitive protein kinase that fulfills key roles during development and in tissue homeostasis. DYRK1A-bound promoters show a higher occurrence of activating chromatin modifications when compared with genes that do not associate with DYRK1A, including high levels of H3K4me3 and H3K4me2 surrounding TSSs or elevated H3K36me3 in the gene body | Homo sapiens |
physiological function | Down syndrome-associated kinase DYRK1A regulates transcription of a subset of genes by associating to their proximal promoter regions and phosphorylating the C-terminal domain of the RNA polymerase II. Protein kinase DYRK1A is recruited to proximal promoters of growth-related genes, genome-wide analysis, overview. DYRK1A recruitment to its target genes is independent of cell growth conditions and the enzyme is recruited to chromatin in both proliferating and resting cells. Enzyme DYRK1A shows ability to activate transcription when tethered to a minimal promoter, relationship between DYRK1A promoter occupancy and the transcriptional activity of its target genes, overview. The TCTCGCGAGA sequence is a regulatory motif in DYRK1A target promoters | Homo sapiens |
