DYRK1A is a serine/threonine kinase with a unique autophosphorylation activity. It contains an N-terminal nuclear localization signal, a serine/threonine kinase domain, and a C-terminal region with multiple splice variants.
DYRK1A regulates neuronal development, cell cycle, and transcription. It phosphorylates transcription factors, cytoskeletal proteins, and signaling molecules. DYRK1A is involved in brain development and cognitive function.
DYRK1A is located in the Down syndrome critical region of chromosome 21 and contributes to DS phenotypes. In AD, DYRK1A phosphorylates tau, APP, and contributes to neurodegeneration. In PD, it may phosphorylate alpha-synuclein. Elevated DYRK1A is found in AD brains.
DYRK1A inhibitors are being developed for AD and DS. Harmine is a potent DYRK1A inhibitor. Newer inhibitors like DYR218 show improved specificity. Challenges include achieving brain penetration and safety.
