MA1-800 detects the alpha Actinin 4 in human and mouse cells.
MA1-800 has been successfully used in Western blot, and immunofluorescence procedures. MA1-800 detects alpha Actinin 4 which has a predicted molecular weight of approximately 105 kDa. Under reducing conditions, MA1-800 detects a monomer of alpha Actinin 4 at approximately 52.5 kDa.
The MA1-800 immunogen is a synthetic peptide corresponding to residues A(884) P Y Q G P D A V P G A L D(897) of human alpha Actin 4.
Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a nonmuscle, alpha actinin isoform which is concentrated in the cytoplasm, and thought to be involved in metastatic processes. Mutations in this gene have been associated with focal and segmental glomerulosclerosis.
