The following text describes a protein:
Function:
Positively regulates actin filament organization and provides mechanical stability to the myofibrils during body wall muscle contraction. Required for the organization of sarcomeric actin filaments and myosin protein myo-3 in striated body wall muscle cells. Not required for assembly of dense bodies, which are a type of integrin-based adhesion structure that link the plasma membrane to thin filaments of myofibrils, in body wall muscle. Not required for the atn-1 protein to localize to the dense bodies.
Subcellular Localization:
Cytoplasm, myofibril, sarcomere. Cytoplasm, cytoskeleton. Note=Localizes to sarcomeres in a punctate pattern. Localizes to actin filaments (thin filaments) close to dense bodies in body wall muscle. Co-localizes with actin filaments in embryos and adults.
