α-Actinin (Sarcomeric) Antibody, anti-human/mouse/rat, FITC, REAfinity™

01MT08687

Clone REA402 recognizes the sarcomeric α-actinin antigen, a 100 kDa actin-binding protein, which occupies a strategic role in the assembly and maintenance of stress fibers of non-muscle cells and the myofibrils of muscle cells. α-actinins have been highly conserved throughout evolution and are largely collinear proteins that share three conserved functional domains. Functionally, α-actinins form antiparallel homodimers with the actin-binding domains on each end of the molecule, allowing crosslinking of actin molecules. Two isoforms of α-actinin have been identified, a muscle-specific sarcomeri
