Dual specificity tyrosine-phosphorylation-regulated kinase 1A is an enzyme that in humans is encoded by the DYRK1A gene.[1] Alternative splicing of this gene generates several transcript variants differing from each other either in the 5' UTR or in the 3' coding region.[2] These variants encode at least five different isoforms.[3]

Contents

Function

DYRK1A is a member of the dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family. This member contains a nuclear targeting signal sequence, a protein kinase domain, a leucine zipper motif, and a highly conservative 13-consecutive-histidine repeat. It catalyzes its autophosphorylation on serine/threonine and tyrosine residues. It may play a significant role in a signaling pathway regulating cell proliferation and may be involved in brain development. This gene is a homolog of Drosophila mnb (minibrain) gene and rat Dyrk gene.[3]

Dyrk1a has also been shown to modulate plasma homocysteine level in a mouse model of overexpression.[4]

Clinical significance

DYRK1A is localized in the Down syndrome critical region of chromosome 21, and is considered to be a strong candidate gene for learning defects associated with Down syndrome.[3] In addition, a polymorphism (SNP) in DYRK1A was found to be associated with HIV-1 replication in monocyte-derived macrophages, as well as with progression to AIDS in two independent cohorts of HIV-1-infected individuals.[2]

Interactions

DYRK1A has been shown to interact with WDR68.[5]
