General annotation (Comments)

Function

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. Ref.3 Ref.6

Subunit structure

Homodimer. Heterodimerizes with MAD2L1 in order to form a tetrameric MAD1L1-MAD2L1 core complex. Perturbation of the original MAD1L1-MAD2L1 structure by the spindle checkpoint may decrease MAD2L1 affinity for MAD1L1. CDC20 can compete with MAD1L1 for MAD2L1 binding, until the attachment and/or tension dampen the checkpoint signal, preventing further release of MAD2L1 on to CDC20. Also able to interact with the BUB1/BUB3 complex and the viral Tax protein. Interacts with TPR and NEK2. Ref.1 Ref.2 Ref.7 Ref.12 Ref.19

Subcellular location

Nucleus. Chromosomecentromerekinetochore. Cytoplasmcytoskeletoncentrosome. Cytoplasmcytoskeletonspindle. Note: 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. Co-localizes with NEK2 at the kinetochore. Ref.1 Ref.7 Ref.12

Tissue specificity

Expressed weakly at G0/G1 and highly at late S and G2/M phase.

Induction

Increased by p53/TP53. Ref.3

Post-translational modification

Phosphorylated; by BUB1. Become hyperphosphorylated in late S through M phases or after mitotic spindle damage. Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.1 Ref.2 Ref.8 Ref.9 Ref.10 Ref.11 Ref.13 Ref.14 Ref.15 Ref.16

Involvement in disease

Note=Defects in MAD1L1 are involved in the development and/or progression of various types of cancer.

Sequence similarities

Belongs to the MAD1 family.

Sequence caution

The sequence AAC52059.1 differs from that shown. Reason: Frameshift at position 663.
