Muscle Actin also known as ACTA1 is a protein that plays a significant role in muscle contraction. It has a molecular weight of approximately 42 kDa. This protein is primarily found in skeletal muscle tissues. Muscle Actin exists in two forms: G-actin a globular monomer and F-actin a filamentous polymer that forms actin filaments. These filaments provide structural support and are involved in muscle contraction through their interaction with myosin.
Muscle Actin interacts with myosin to facilitate muscle contraction. It is an important component of the thin filament within the sarcomere the basic unit of muscle fiber. Muscle Actin is part of a complex and this complex includes other important proteins like tropomyosin and troponin. These proteins regulate the interaction between actin and myosin enabling the muscle contraction process. Muscle Actin's polymerization and depolymerization dynamics are important for the regulation of cellular movement and structural integrity.
Muscle Actin is essential for the actin-myosin contractile machinery in muscle cells which is part of the sarcomere assembly pathway. This process involves other proteins such as myosin heavy chain and tropomyosin which are important for muscle contraction. Another important pathway is the Rho GTPase signaling pathway which controls actin filament assembly and is involved in a variety of cellular processes including muscle contraction and cell motility.
Muscle Actin mutations link to certain muscle-related diseases such as nemaline myopathy and congenital myopathies. Nemaline myopathy involves the presence of rod-like structures in muscle fibers and it results from anomalies in actin filaments. Muscle Actin also associates with cardiac muscle conditions when there are mutations affecting cardiac actin structure or function. This reveals the connection between Muscle Actin tropomyosin and troponin in muscle contraction efficiency and structural integrity contributing to these diseases' pathogenesis.

Muscle Actin Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) staining using rabbit Anti-muscle Actin antibody
IHC image of unpurified ab156302 staining muscle Actin in human colon* formalin fixed paraffin embedded tissue sections, performed on a Leica Bond. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with unpurified ab156302, 5μg/ml working concentration, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. No primary antibody was used in the secondary only control (shown on the inset).
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Sevoflurane downregulated PPAR-γ expression. (a-b) Gene Set Enrichment Analysis plots for the peroxisome proliferator-activated receptor- (PPAR-) γ target gene set and PPAR signaling gene set in the microarray dataset are shown. The PPAR-γ target gene signature and PPAR signaling pathway signature were highly enriched in control samples than in sevoflurane-treated samples, thus indicating that PPAR-γ signaling is downregulated by sevoflurane. (c) The heat map of PPAR-γ target genes in control and sevoflurane-treated samples is shown. (d) Exposure to 3% sevoflurane for 2 h daily from P6 to P8 downregulated the expression of PPAR-γ in the brain tissue of mice and the hippocampal tissues of mice. (e) Quantification of western blots (n = 6) confirmed that sevoflurane downregulated the expression of PPAR-γ. (f) Quantification of western blots (n = 6) confirmed that sevoflurane downregulated the expression of PPAR-γ.
