Immunohistochemistry (PFA perfusion fixed frozen sections) - Anti-ANK-3 antibody [2A8] (AB315200)

Immunofluorescent analysis of cortex section of rat brain stained with ab315200, dilution 1 : 2,000 in green and costained with rabbit pAb to NF-L, RPCA-NF-L, dilution 1 : 5,000 in red. The blue is Hoechst staining of nuclear DNA. Following transcardial perfusion of rat with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45μM, and free-floating sections were stained with above antibodies. The ab315200 antibody stains the axonal initial segments, while the RPCA-NF-L antibody labels dendrites and axons of neuronal cells.

Western blot - Anti-ANK-3 antibody [2A8] (AB315200)

Western blot analysis of different tissue and cell lysates using ab315200, dilution 1 : 2,000 in green : [1] protein standard (red), [2] NIH-3T3, [3] C6, [4] HEK293, [5] HeLa, [6] SH-SY5Y cells, [7] rat brain, and [8] mouse brain lysates. Bands at ~190kDa represent ankyrin3 splice variants, higher molecular weight bands at 270kDa and 480kDa can be seen on longer exposure. Lower molecular weight bands are likely proteolytic fragments.

ANK-3 also known as ankyrin-G has a significant role in maintaining the structural integrity and function of cells. It is a cytoskeletal protein with a molecular weight approximately 220 kDa. ANK-3 is expressed in a wide variety of tissues with high expression in the brain heart and skeletal muscle. It links integral membrane proteins to the underlying spectrin-actin cytoskeleton stabilizing the cellular membrane and organizing membrane domains.
Biological function summary

The interaction of ANK-3 with various proteins contributes to cellular activities. ANK-3 binds to key molecules like ion channels and cell adhesion molecules making it an integral part of the cell membrane-cytoskeleton interface. It is a member of the ankyrin family which includes ANK and ANK-106 providing different isoforms like ANK-3 isoforms that contribute to its diverse functional roles. ANK-3 associates with specific complexes facilitating the localization of nodes of Ranvier in axons and maintaining polarized distribution of channels in neurons.

Pathways

ANK-3 serves a major function in the neurobiological and cardiac pathways. It plays a role in the regulation of action potentials in neurons through its interaction with ion channels and is essential in cardiac muscle function by associating with proteins involved in heart rhythm regulation. ANK-3 through these pathways exhibits functional relationships with proteins such as ANK-2 and 2a8 which further influence cellular excitability and signaling.

Disruptions in ANK-3 function associate with neuropsychiatric disorders and cardiac arrhythmias. ANK-3 dysfunction has been implicated in bipolar disorder where genetic variations may affect its molecular interactions leading to altered neuronal signaling. In cardiac contexts improper expression or mutations of ANK-3 can contribute to arrhythmogenic disorders sometimes in coordination with proteins such as n106 and other ankyrins impacting cardiac stability.

Target data

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 (PubMed : 7836469). In skeletal muscle, required for costamere localization of DMD and betaDAG1 (By similarity). Regulates KCNA1 channel activity in function of dietary Mg(2+) levels, and thereby contributes to the regulation of renal Mg(2+) reabsorption (PubMed : 23903368). Required for intracellular adhesion and junctional conductance in myocytes, potentially via stabilization of GJA1/CX43 protein abundance and promotion of PKP2, GJA1/CX43, and SCN5A/Nav1.5 localization to cell-cell junctions (By similarity).. Isoform 5. May be part of a Golgi-specific membrane cytoskeleton in association with beta-spectrin.
