Disease

[ANK3_HUMAN] Intellectual disability - hypotonia - spasticity - sleep disorder;Schizophrenia. Genetic variations in ANK3 may be associated with autism spectrum disorders susceptibility. The disease is caused by mutations affecting the gene represented in this entry. A homozygous deletion in ANK3 predicted to result in frameshift and premature truncation, has been shown to be the cause of moderate intellectual disability, an ADHD-like phenotype and behavioral problems in a consanguineous family (PubMed:23390136).^[1]

Function

[ANK3_HUMAN] In skeletal muscle, required for costamere localization of DMD and betaDAG1 (By similarity). Membrane-cytoskeleton linker. May participate in the maintenance/targeting of ion channels and cell adhesion molecules at the nodes of Ranvier and axonal initial segments. Isoform 5: May be part of a Golgi-specific membrane cytoskeleton in association with beta-spectrin.

Publication Abstract from PubMed

Ankyrins (Ank) are a ubiquitously expressed family of multifunctional membrane adapter proteins. Ankyrin G (AnkG) is critical for assembling and maintenance of the axon initial segment. Here we present the 2.1 A crystal structure of human AnkG death domain (hAnkG-DD). The core death domain is composed of six alpha-helices and three 310 -helices. It forms a hydrophobic pocket on the surface of the molecule. The C-terminal tail of the hAnkG-DD curves back to have the aromatic ring of a phenylalanine residue, Phe100 insert into this pocket, which anchors the flexible tail onto the core domain. Related DDs were selected for structure comparison. The major variations are at the C-terminal region, including the alpha6 and the long C-terminal extension. The results of size exclusion chromatography and analytical ultracentrifugation suggest that hAnkG-DD exists as monomer in solution. Our work should help for the future investigation of the structure-function of AnkG.Proteins 2014. (c) 2014 Wiley Periodicals, Inc.
