Description générale
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
Actions biochimiques/physiologiques
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.

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

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

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 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

Online label-free monitoring of in-vitro differentiation of stem cells remains a major challenge in stem cell research. In this paper we report the use of Raman micro-spectroscopy (RMS) to measure time- and spatially-resolved molecular changes in intact embryoid bodies (EBs)
