ICC/IF Use at an assay dependent dilution.


  • FunctionComponent of the spindle-assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. May recruit MAD2L1 to unattached kinetochores. Has a role in the correct positioning of the septum. Required for anchoring MAD2L1 to the nuclear periphery. Binds to the TERT promoter and represses telomerase expression, possibly by interfering with MYC binding.
  • Tissue specificityExpressed weakly at G0/G1 and highly at late S and G2/M phase.
  • Involvement in diseaseDefects in MAD1L1 are involved in the development and/or progression of various types of cancer.
  • Sequence similaritiesBelongs to the MAD1 family.
  • Post-translational
    Phosphorylated; by BUB1. Become hyperphosphorylated in late S through M phases or after mitotic spindle damage.
  • Cellular localizationNucleus. Chromosome > centromere > kinetochore. Cytoplasm > cytoskeleton > microtubule organizing center > centrosome. Cytoplasm > cytoskeleton > spindle. From the beginning to the end of mitosis, it is seen to move from a diffusely nuclear distribution to the centrosome, to the spindle midzone and finally to the midbody. Colocalizes with NEK2 at the kinetochore.
