General description

Anti-Actinin α Antibody detects endogenous levels of total Actinin α protein.
α-actinin-2 (ACTN2) is a myofibrillar protein that is expressed in cardiac muscle. It is located at the the Z disk. The ACTN2 gene is mapped to human chromosome 1q43.

Immunogen

The antiserum was produced against synthesized peptide derived from human Actinin alpha-2/3.

Immunogen Range: 31-80

Biochem/physiol Actions

Mutation in the α-actinin-2 (ACTN2) gene leads to hypertrophic cardiomyopathy. It is essential in cross-linking actin and titin filaments in the Z-disc. ACTN2 is associated with a number of cytoskeletal and signaling molecules and is involved in the structural and modulatory roles in the organization of the cytoskeleton and muscle contraction.

Mutations in cardiac myosin binding protein C (cMyBPC) are a major cause of hypertrophic cardiomyopathy (HCM). In particular, a single amino acid substitution of tyrosine to serine at residue 237 in humans (residue 235 in mice) has been linked to

Cardiac myosin binding protein C (cMyBPC) is an 11-domain sarcomeric protein (C0-C10) integral to cardiac muscle regulation. In vitro studies have demonstrated potential functional roles for regions beyond the N-terminus. However, the in vivo contributions of these domains are mostly

Decreased cardiac myosin-binding protein C (cMyBPC) expression due to inheritable mutations is thought to contribute to the hypertrophic cardiomyopathy (HCM) phenotype, suggesting that increasing cMyBPC content is of therapeutic benefit. In vitro assays show that cMyBPC N-terminal domains (NTDs) contain
