ELISA - Recombinant Human Alpha Skeletal Muscle Actin protein (AB157838)

1 ug per mL of recombinant protein ab157838 and ab157841 were immobilised in PBS on an ELISA plate overnight. After blocking in 5% BSA, primary antibody (ab119952) was added in a concentration range of 0.017-1000 ng per mL.

Pre-absorbed secondary antibody goat anti-rabbit IgG H&L (HRP, ab97080) was used at 1/20000 dilution.

Alpha Skeletal Muscle Actin also known as Actin Alpha 1 Actin Alpha and Actin Protein is a highly conserved protein important for muscle function. It has a molecular mass of approximately 42 kDa. This protein is expressed in skeletal muscle tissues and is an essential component of muscle cell's cytoskeleton. The actin family to which Alpha Skeletal Muscle Actin belongs is integral for maintaining cell shape integrity and movement. This isoform of actin is especially significant in forming thin filaments in muscle fibers which are essential for muscle contraction.
Biological function summary

Alpha Skeletal Muscle Actin plays an essential role in the contractile apparatus of muscle cells. It exists as part of the actin filament complex interacting closely with myosin motor proteins. This interaction powers the sliding mechanism that enables muscle contraction and relaxation. Alpha-actin is responsible for mechanical stiffness and tension within muscle tissues enabling muscle fibers to withstand physical stress. The protein's structural role in muscle cells makes it indispensable for proper muscle function and muscle fiber stability.

Pathways

Alpha Skeletal Muscle Actin is deeply involved in the cytoskeletal organization and muscle contraction pathways. It is pivotal in the actin-myosin interaction pathway where it binds to troponin and tropomyosin which regulate muscle contraction cycles. Within these pathways the protein ensures coordinated muscle contractions alongside other proteins like myosin heavy chain and tropomyosin. These interactions coordinate muscle contraction maintaining muscle tone and health.

Alpha Skeletal Muscle Actin mutations have a direct link to various myopathies including actin myopathy and nemaline myopathy. These conditions often result in muscle weakness and occasionally muscle degeneration. The protein's malfunction may also connect to cardiomyopathies due to its important role in muscle function. Research suggests that protein interactions with dystrophin another muscle-associated protein might further elucidate its role in these muscle disorders. Actin dysfunction in these conditions highlights the necessity for healthy actin filaments for skeletal muscle integrity and function.

General info

Function

Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.

Sequence similarities

Belongs to the actin family.

Post-translational modifications

Oxidation of Met-46 and Met-49 by MICALs (MICAL1, MICAL2 or MICAL3) to form methionine sulfoxide promotes actin filament depolymerization. MICAL1 and MICAL2 produce the (R)-S-oxide form. The (R)-S-oxide form is reverted by MSRB1 and MSRB2, which promotes actin repolymerization.. Monomethylation at Lys-86 (K84me1) regulates actin-myosin interaction and actomyosin-dependent processes. Demethylation by ALKBH4 is required for maintaining actomyosin dynamics supporting normal cleavage furrow ingression during cytokinesis and cell migration.. Actin, alpha skeletal muscle, intermediate form. N-terminal cleavage of acetylated cysteine of intermediate muscle actin by ACTMAP.. Methylated at His-75 by SETD3.. (Microbial infection) Monomeric actin is cross-linked by V.cholerae toxins RtxA and VgrG1 in case of infection: bacterial toxins mediate the cross-link between Lys-52 of one monomer and Glu-272 of another actin monomer, resulting in formation of highly toxic actin oligomers that cause cell rounding (PubMed:19015515). The toxin can be highly efficient at very low concentrations by acting on formin homology family proteins: toxic actin oligomers bind with high affinity to formins and adversely affect both nucleation and elongation abilities of formins, causing their potent inhibition in both profilin-dependent and independent manners (PubMed:26228148).
