Ank2 Gene Summary [Rat]
Enables protein kinase binding activity and transmembrane transporter binding activity. A structural constituent of cytoskeleton. Involved in paranodal junction assembly and response to methylmercury. Predicted to be located in several cellular components, including T-tubule; basolateral plasma membrane; and myofibril. Predicted to be active in paranodal junction. Predicted to be extrinsic component of cytoplasmic side of plasma membrane. Biomarker of transient cerebral ischemia. Human ortholog(s) of this gene implicated in ankyrin-B-related cardiac arrhythmia; atrial fibrillation; long QT syndrome; and sick sinus syndrome. Orthologous to human ANK2 (ankyrin 2).

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 Ank2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
