Anti-CASC5 KNL1 Antibody

Kinetochore scaffold 1; ALL1-fused gene from chromosome 15q14 protein; AF15q14; Bub-linking kinetochore protein; Blinkin; Cancer susceptibility candidate gene 5 protein; Cancer/testis antigen 29; CT29; Kinetochore-null protein 1; Protein CASC5; Protein D40/AF15q14; KNL1

Highly expressed in testis, where it is localized in germ cells, in particular in spermatocytes and in the pre-acrosome of round spermatids. Detected in the acrosome of ejaculated spermatozoa. Detected in adult thymus, bone marrow, colon, small intestine, appendix and placenta, and in fetal liver and thymus.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .

Performs two crucial functions during mitosis: it is essential for spindle-assembly checkpoint signaling and for correct chromosome alignment. Required for attachment of the kinetochores to the spindle microtubules. Directly links BUB1 and BUB1B to kinetochores. Part of the MIS12 complex, which may be fundamental for kinetochore formation and proper chromosome segregation during mitosis. Acts in coordination with CENPK to recruit the NDC80 complex to the outer kinetochore.

Nucleus. Chromosome, centromere, kinetochore. Weakly expressed in interphase nuclei. Expression increases from prophase to late anaphase, but greatly diminishes from the telophase and cytokinesis to early G1 phase of cell cycle.
