Gene Information

General description

α-Actinin exists as a rod-shaped antiparallel dimer with two elongated subunits. The domain region contains an N-terminal actin-binding domain with tandem calponin homology domains, a central tandem 3-helix motifs, and EF-hand motifs at C-terminus. It belongs to the spectrin superfamily and is localized in actin structures.

Application

α-Actinin from chicken gizzard has been used:
  • as an antigen to coat plates for the capture of anti-actinin antibody using enzyme-linked immunosorbent assay (ELISA) from tumor cell line clones
  • in in vitro motility experiments to test its effect on actin filament movement
  • to coat cantilevers for strengthening fluorescently labeled actin filaments in force measurement studies

Biochem/physiol Actions

α-Actinin binds actin and has the ability to crosslink actin cytoskeleton. It also plays a key role in the structural maintenance of the Z-disk of striated muscle.

Packaging

Package size based on protein content

Physical form

Suspension in 2 M (NH4)2SO4 containing 20 mM Tris acetate, pH 7.6, 20 mM sodium chloride, 0.1 mM EDTA, 15 mM β-mercaptoethanol and 1 mM phenylmethylsulfonyl fluoride

Preparation Note

Alpha-actinin ammonium sulfate suspension should be mixed sufficiently and further diluted prior to use. Protein precipitate will be present in solution with high protein concentrations.

Prepared using a modification of the procedure of Neidel, J.E. and Cuatrecasas, P., Biochem. Biophys. Res. Commun., 91, 152 (1979).

Cryoelectron microscopy was used to obtain a 3-D image at 2.0 nm resolution of 2-D arrays of smooth muscle alpha-actinin. The reconstruction reveals a well-resolved long central domain with 90 degrees of left-handed twist and near 2-fold symmetry. However, the

The Drosophila Alp/Enigma family protein Zasp52 localizes to myotendinous junctions and Z-discs. It is required for terminal muscle differentiation and muscle attachment. Its vertebrate ortholog ZASP/Cypher also localizes to Z-discs, interacts with α-actinin through its PDZ domain, and is involved

Mitochondria are fundamentally important in cell function, and their malfunction can cause the development of cancer, cardiovascular disease, and neuronal disorders. Myosin 19 (Myo19) shows discrete localization with mitochondria and is thought to play an important role in mitochondrial dynamics

The contribution of three actin cross-linking proteins, alpha-actinin (alphaA), gelation factor (ABP-120), and the 34 kDa actin-bundling protein to cellular functions has been studied in three single mutant (alphaA-, 120-, and 34-) and three double mutant (alphaA-/120-, 34-/alphaA-, 34-/120-) strains

Muscle, motor unit and muscle fibre type-specific differences in force-generating capacity have been investigated for many years, but there is still no consensus regarding specific differences between slow- and fast-twitch muscles, motor units or muscle fibres. This is probably related
