This gene encodes a member of the Dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family. This member contains a nuclear targeting signal sequence, a protein kinase domain, a leucine zipper motif, and a highly conservative 13-consecutive-histidine repeat. It catalyzes its autophosphorylation on serine/threonine and tyrosine residues. It may play a significant role in a signaling pathway regulating cell proliferation and may be involved in brain development. This gene is a homolog of Drosophila mnb (minibrain) gene and rat Dyrk gene. It is localized in the Down syndrome critical region of chromosome 21, and is considered to be a strong candidate gene for learning defects associated with Down syndrome. Alternative splicing of this gene generates several transcript variants differing from each other either in the 5' UTR or in the 3' coding region. These variants encode at least five different isoforms. [provided by RefSeq, Jul 2008]
GeneCards Summary for DYRK1A Gene
DYRK1A (Dual Specificity Tyrosine Phosphorylation Regulated Kinase 1A) is a Protein Coding gene. Diseases associated with DYRK1A include Mental Retardation, Autosomal Dominant 7 and Intellectual Disability Syndrome Due To A Dyrk1a Point Mutation. Among its related pathways are Cell Cycle, Mitotic and T-Cell Receptor and Co-stimulatory Signaling. Gene Ontology (GO) annotations related to this gene include identical protein binding and protein kinase activity. An important paralog of this gene is DYRK1B.
UniProtKB/Swiss-Prot Summary for DYRK1A Gene
Dual-specificity kinase which possesses both serine/threonine and tyrosine kinase activities. May play a role in a signaling pathway regulating nuclear functions of cell proliferation. Modulates alternative splicing by phosphorylating the splice factor SRSF6 (By similarity). Exhibits a substrate preference for proline at position P+1 and arginine at position P-3. Has pro-survival function and negatively regulates the apoptotic process. Promotes cell survival upon genotoxic stress through phosphorylation of SIRT1. This in turn inhibits TP53 activity and apoptosis (By similarity).
Dual-specificity tyrosine phosphorylation-regulated kinases (DYRKs) are conserved serine/threonine kinases. DYRKs have been implicated in cell survival, proliferation and differentiation, and in the pathology of Down Syndrome and Alzheimer's disease.
