Ankyrin 2, neuronal, also known as ANK2, is a protein which in humans is encoded by the ANK2 gene.[1][2]

Function

The protein encoded by this gene is required for targeting and stability of Na+/Ca++ exchanger 1 in cardiomyocytes. Mutations in this gene cause long QT syndrome 4.[3] Multiple transcript variants encoding different isoforms have been described.[1]

Ankyrin family

The protein encoded by the ANK2 gene is a member of the ankyrin family of proteins that link the integral membrane proteins to the underlying spectrin-actin cytoskeleton. Ankyrins play key roles in activities such as cell motility, activation, proliferation, contact and the maintenance of specialized membrane domains. Most ankyrins are typically composed of three structural domains: an amino-terminal domain containing multiple ankyrin repeats; a central region with a highly conserved spectrin binding domain; and a carboxy-terminal regulatory domain which is the least conserved and subject to variation.[1]
