Dyrk1a Gene Summary [Rat]
Enables protein serine/threonine kinase activity and protein tyrosine kinase activity. Involved in several processes, including protein phosphorylation; regulation of RNA splicing; and regulation of cardiac muscle tissue growth. Located in nuclear speck. Used to study congestive heart failure and dilated cardiomyopathy. Biomarker of hyperhomocysteinemia; myocardial infarction; and renovascular hypertension. Human ortholog(s) of this gene implicated in Down syndrome; autism spectrum disorder; autosomal dominant intellectual developmental disorder 7; and intellectual disability. Orthologous to human DYRK1A (dual specificity tyrosine phosphorylation regulated kinase 1A). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Dyrk1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
