Anti-actin like 7B antibodies are used in the immunodetection of the protein encoded by the ACTL7B gene. In humans, the canonical protein has a reported length of 415 amino acid residues and a mass of 45.2 kDa. Its subcellular localization is in the cytoplasm. The actin like 7B protein is a member of the Actin protein family. Other names for this target antigen include actin-like protein 7B, actin-like 7-beta, testis tissue sperm-binding protein Li 43a, and Tact1.
