== Disease ==
[https://www.uniprot.org/uniprot/DYR1A_HUMAN DYR1A_HUMAN] Defects in DYRK1A are the cause of mental retardation autosomal dominant type 7 (MRD7) [MIM:[https://omim.org/entry/614104 614104]. A disease characterized by primary microcephaly, severe mental retardation without speech, anxious autistic behavior, and dysmorphic features, including bitemporal narrowing, deep-set eyes, large simple ears, and a pointed nasal tip. Mental retardation is characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period.<ref>PMID:21294719</ref> 
== Function ==
[https://www.uniprot.org/uniprot/DYR1A_HUMAN DYR1A_HUMAN] May play a role in a signaling pathway regulating nuclear functions of cell proliferation. Phosphorylates serine, threonine and tyrosine residues in its sequence and in exogenous substrates.<ref>PMID:8769099</ref>

== Publication Abstract from PubMed ==
The serine/threonine kinase DYRK1A has been implicated in regulation of a variety of cellular processes associated with cancer progression, including cell cycle control, DNA damage repair, protection from apoptosis, cell differentiation, and metastasis. In addition, elevated-level DYRK1A activity has been associated with increased severity of symptoms in Down's syndrome. A selective inhibitor of DYRK1A could therefore be of therapeutic benefit. We have used fragment and structure-based discovery methods to identify a highly selective, well-tolerated, brain-penetrant DYRK1A inhibitor which showed in vivo activity in a tumor model. The inhibitor provides a useful tool compound for further exploration of the effect of DYRK1A inhibition in models of disease.
