Opis ogólny

α-Actinin is a 100kDa actin-binding protein that is found in muscle as well as non-muscle cells. Rabbit anti-α-actinin antibody stains α-actinin in cell cultures using indirect immunofluorescence. The antibody reacts best with cultured chicken fibroblasts, however, adequate labeling may also be obtained with cells of other species. In an immunoblot assay, the antiserum specifically stains the α-actinin band.
α-Actinin is a member of the spectrin superfamily. It consists of an antiparallel homodimer, with an N-terminal actin-binding domain (ABD), a central domain of four spectrin-like repeats (SRs), and a C-terminal calmodulin-like domain (CAMD) with two pairs of EF-hand motifs (EFs). α-Actinin exists in four isoforms: α-actinin 1, α-actinin 2, α-actinin 3 and α-actinin 4. In smooth muscles, α-actinin is present in dense bodies and plaques whereas, in normal skeletal muscles, it is associated with Z-discs that define muscle sarcomere.

Specyficzność

Anti-α-Actinin specifically stains α-actinin in cell cultures using indirect immunfluorescent labeling techniques. The antibody reacts best with cultured chicken fibroblasts, however adequate labeling may also be obtained with cells of other species.

Immunogen

α-actinin from chicken gizzard

Zastosowanie

Anti-Actinin antibody was used to detect actinin in human mesangial cells. Cells were first grown on glass cover slips, fixed in cold methanol and permeabilized with 3.5% paraformaldehyde/0.1% Tween-20 for 5 min at room temperature.
Rabbit anti-α-actinin antibody has been used for:
  • co-immunoprecipitation studies
  • immunoblotting studies
  • immunofluorescence

Działania biochem./fizjol.

α-Actinin is an actin-crosslinking Z-disk protein. It plays a vital role in linking the cytoskeleton to different transmembrane proteins in a variety of junctions. α-Actinin modulates receptor activities and serves as a cytoskeleton scaffold for diverse signaling pathways. It is implicated in muscle contraction.

Postać fizyczna

Supplied as a liquid with 0.1% sodium azide as a preservative.

Przechowywanie i stabilność

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

Integrins are a large family of integral membrane proteins that function in signal transduction in animal systems. These proteins are conserved in vertebrates, invertebrates, and fungi. Evidence from previous research suggests that integrin-like proteins may be present in plants as

Ligand-driven dimerizations of ErbB receptor subunits fulfill a fundamental role in their activation. We have used the number and brightness analysis technique to investigate the existence of preformed ligand-independent dimers and clusters and to characterize the initial steps in the

The N-terminal actin-binding domain of alpha-actinin is connected to the C-terminal EF-hands by a rod domain. Because of its ability to form dimers, alpha-actinin can cross-link actin filaments in muscle cells as well as in nonmuscle cells. In the prototypic
