Anti-actin like 7A antibodies are used in the immunodetection of the protein encoded by the ACTL7A gene. In humans, the canonical protein has a reported length of 435 amino acid residues and a mass of 48.6 kDa. Its subcellular localization is in the nucleus, cytoplasmic vesicles, golgi, and cytoplasm. It is reported to be highly expressed in testis. A member of the Actin protein family, it is believed to play an important role in formation and fusion of Golgi-derived vesicles during acrosome biogenesis. Other names for this target antigen include actin-like 7-alpha, testicular secretory protein Li 3, and actin-like protein 7A.
