The following Actinin, alpha 4 ELISA kits are useful research tools for the measurement of actinin alpha 4 in biological samples. In humans this protein is encoded by the ACTN4 gene. This protein has been described to function in cytoskeleton organization and the regulation of cell migration. The canonical protein structure is reported to have an amino acid length of 911 residues, a mass of 104.9 kDa, and is a member of the Alpha-actinin protein family. Its subcellular location is known to be in the nucleus and cytoplasm. In addition, it is widely expressed across many tissue types. As many as 3 protein isoforms have been reported. The gene encoding this protein has been associated with the disease, Focal segmental glomerulosclerosis. This protein may also be known as FSGS, FSGS1, alpha-actinin-4, focal segmental glomerulosclerosis 1, non-muscle alpha-actinin 4, and ACTININ-4.
