Anti-SKA1 antibodies are used in the immunodetection of the protein spindle and kinetochore associated complex subunit 1. In humans, the canonical protein has a reported length of 255 amino acid residues and a mass of 29.5 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SKA1 protein family, SKA1 is a known component of the SKA1 complex, a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. Synonyms for this target antigen include spindle and kinetochore-associated protein 1 and spindle and KT (kinetochore) associated 1. SKA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some SKA1 antibodies may have been used in research and have associated citations. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
