Target Species

Human

Target Name

MAD2L1

Target Full Name

Mitotic spindle assembly checkpoint protein MAD2A

Target Function

Component of the spindle-assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. In the closed conformation (C-MAD2) forms a heterotetrameric complex with MAD1L1 at unattached kinetochores during prometaphase, the complex recruits open conformation molecules of MAD2L1 (O-MAD2) and then promotes the conversion of O-MAD2 to C-MAD2. Required for the execution of the mitotic checkpoint which monitors the process of kinetochore-spindle attachment and inhibits the activity of the anaphase promoting complex by sequestering CDC20 until all chromosomes are aligned at the metaphase plate.

Target Subcellular Location

Nucleus. Chromosome, centromere, kinetochore. Cytoplasm. Cytoplasm, cytoskeleton, spindle pole.

Target Protein Families

MAD2 family

Target Synonyms

HsMAD2; MAD 2; MAD2 like 1; MAD2 mitotic arrest deficient like 1; MAD2-like protein 1; Mad2l1; MD2L1_HUMAN; Mitotic arrest deficient 2-like protein 1; Mitotic spindle assembly checkpoint protein MAD2A; REV7

Target Background

MAD2L1 is a component of the mitotic spindle assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. MAD2L1 is related to the MAD2L2 gene located on chromosome 1. A MAD2 pseudogene has been mapped to chromosome 14.
