Disease

[DYR1A_HUMAN] Defects in DYRK1A are the cause of mental retardation autosomal dominant type 7 (MRD7) [MIM: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.^[1]

Function

[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.^[2]

Publication Abstract from PubMed

DYRK1A has emerged as a potential target for therapies of Alzheimer's disease using small molecules. On the basis of the observation of selective DYRK1A inhibition by firefly d-luciferin, we have explored static and dynamic structural properties of fragment sized variants of the benzothiazole scaffold with respect to DYRK1A using X-ray crystallography and NMR techniques. The compounds have excellent ligand efficiencies and show a remarkable diversity of binding modes in dynamic equilibrium. Binding geometries are determined in part by interactions often considered "weak", including "orthogonal multipolar" types represented by, for example, F-CO, sulfur-aromatic, and halogen-aromatic interactions, together with hydrogen bonds that are modulated by variation of electron withdrawing groups. These studies show how the benzothiazole scaffold is highly promising for the development of therapeutic DYRK1A inhibitors. In addition, the subtleties of the binding interactions, including dynamics, show how full structural studies are required to fully interpret the essential physical determinants of binding.
