General description

α-Actinin is a 100kDa actin-binding protein that is found in muscle as well as non-muscle cells. 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 sarcomeres. The gene encoding α-actinin is mapped to the human chromosome 11q13.2. α-Actinin belongs to the spectrin protein superfamily.
α-Actinin dimerizes in an antiparallel fashion via interaction of the central rod domains. Four isoforms are found in human and mice. α-actinin-1 is ubiquitously expressed and located primarily in focal adhesions, whereas α-actinin-4 is present in certain membrane ruffles and seems to play a role in endocytosis and tumor cell motility.
ACTN1 (α-actinin-1) and ACTN4 (α-actinin-4) encodes non-muscle proteins, while ACTN2 (α-actinin-2) and ACTN3 (α-actinin-3) encodes muscle proteins.
Monoclonal Anti-α-Actinin (Sarcomeric) shows wide reactivity, as it binds to human, bovine, pig, sheep, rabbit, goat, hamster, cat, rat, mouse, dog, chicken, lizard, snake, frog and fish α-actinin.

Specificity

Monoclonal Anti-α-Actinin (Sarcomeric) specifically recognizes α-skeletal muscle actinin and α-cardiac muscle actinin.

Immunogen

Purified rabbit skeletal α actinin.

Application

Mouse Monoclonal Anti-alpha-Actinin (Sarcomeric) antibody has been used for immunocytochemical (1:800) and immunohistochemical (1:100) applications.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Immunocytochemistry (1 paper)
Immunofluorescence (2 papers)
Immunohistochemistry (1 paper)
Western blot analysis of transfected HEK-293 cells were performed to evaluate actinin expression using monoclonal mouse anti-actinin antibody.

Biochem/physiol Actions

α-Actinin maintains the structure of cytoskeletal organization and regulates muscle contraction. α-Actinin functions as an actin crosslinker and promotes cell migration. Mutations in the α-actinin gene is observed in heterogeneous hypertrophic cardiomyopathy and in juvenile onset atrial fibrillation.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month.
For extended storage, freeze at -20 °C in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
