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).

Critical illness myopathy (CIM) represents a common consequence of modern intensive care, negatively impacting patient health and significantly increasing health care costs; however, there is no treatment available apart from symptomatic and supportive interventions. The chaperone co-inducer BGP-15 has previously

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

A hallmark of biopolymer networks is their sensitivity to stress, reflected by pronounced nonlinear elastic stiffening. Here, we demonstrate a distinct dynamical nonlinearity in biopolymer networks consisting of filamentous actin cross-linked by α-actinin-4. Applied stress delays the onset of relaxation

The assembly of proteins into multidomain complexes is critical for their function. In eukaryotic nonmuscle cells, regulation of the homodimeric actin cross-linking protein α-actinin-4 (ACTN4) during cell migration involves signaling receptors with intrinsic tyrosine kinase activity, yet the underlying molecular
