Mark2 Gene Summary [Rat]
Enables protein serine/threonine kinase activity and tau protein binding activity. Involved in several processes, including establishment or maintenance of cell polarity regulating cell shape; generation of neurons; and protein phosphorylation. Located in membrane. Is active in glutamatergic synapse. Orthologous to human MARK2 (microtubule affinity regulating kinase 2). [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 Mark2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
