  • inhibiting the expression of REST(a key regulator of pluripotency and neuronal differentiation), an alteration that persists in trisomy 21 from undifferentiated embryonic stem (ES) cells to adult brain (deregulation of REST is a very early pathological consequence of trisomy 21 with potential to disturb the development of all embryonic lineages)
  • negative regulator of the intrinsic apoptotic pathway in the developing retina (phosphorylates caspase-9 on threonine residue 125, and this phosphorylation event is crucial to protect retina cells from apoptotic cell death)

  • DYRK1A controls the transition from proliferation to quiescence during lymphoid development by destabilizing CCND3
  • dose-specific DYRK1A expression and activity appears to be critical for the hyperplastic and hypertrophic growth of the developing heart
  • DYRK1A expression decreases cell survival efficiency in response to DNA damage, suggesting a tumor suppressive role for this kinase
  • is important for both kidney development and function
  • dual kinase that can phosphorylate its own activation loop on tyrosine residue and phosphorylate its substrates on threonine and serine residues
  • DYRK1A and CEP97 coordinate with PLK1 to promote Separase function to properly form multicilia in multiciliated cells (MCCs)
  • involved in many biological processes during development and in adulthood
  • plays a role in major developmental steps of brain development, controlling the proliferation of neural progenitors, the migration of neurons, their dendritogenesis and the function of the synapse

  • Dyrk1a overexpression in primary mouse cortical neurons induced severe reduction of the dendritic growth and dendritic complexity
  • increased expression of phospho-Thr(192)-RCAN1 was observed in the brains of transgenic mice overexpressing the Dyrk1A protein
