Dyrk1a (Q63470) - Overview - Molecular Target Synopsis


Dyrk1a, Dual specificity tyrosine-phosphorylation-regulated kinase 1A
Enzyme Classification
UniProt Q63470

Also Known as DYR1A_RAT, Dyrk1a, Dyrk

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. Interacts with RANBP9. Interacts with RAD54L2/ARIP4. Interacts with CRY2 (By similarity). Interacts with WDR68 (By similarity). Interacts with SRSF6 (PubMed:22767602). Interacts with SIRT1.
