Anti-Kinetochore localized astrin (SPAG5) binding protein antibodies are available from several suppliers. In humans, this protein is encoded by the gene KNSTRN. The protein may also be known as C15orf23, SKAP, HSD11, TRAF4AF1, small kinetochore-associated protein, and TRAF4 associated factor 1. The expected protein mass is 35.4 kDa, but there are 3 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine, monkey, mouse and rat.
