MAD1L1 Component 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. Belongs to the MAD1 family. Expressed weakly at G0/G1 and highly at late S and G2/M phase. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
