CC -!- FUNCTION: Component of the spindle-assembly checkpoint that prevents
CC the onset of anaphase until all chromosomes are properly aligned at the
CC metaphase plate (By similarity). In the closed conformation (C-MAD2)
CC forms a heterotetrameric complex with MAD1L1 at unattached kinetochores
CC during prometaphase, and recruits an open conformation of MAD2L1 (O-
CC MAD2) which then promotes the conversion of O-MAD2 to C-MAD2 (By
CC similarity). Required for the execution of the mitotic checkpoint which
CC monitors the process of kinetochore-spindle attachment and inhibits the
CC activity of the anaphase promoting complex by sequestering CDC20 until
CC all chromosomes are aligned at the metaphase plate (By similarity).
CC {ECO:0000250|UniProtKB:Q13257}.
CC -!- SUBUNIT: Monomer and homodimer (By similarity). Heterodimerizes with
CC MAD2L1 in order to form a tetrameric MAD1L1-MAD2L1 core complex (By
CC similarity). In the closed and open conformation, interacts with MAD1L1
CC (By similarity). Formation of a heterotetrameric core complex
CC containing two molecules each of MAD1L1 and of MAD2L1 promotes binding
CC of another molecule of MAD2L1 to each MAD2L1, resulting in a
CC heterohexamer (By similarity). Interacts with MAD2L1BP (By similarity).
CC Interacts with ADAM17/TACE (By similarity). Interacts with CDC20 (By
CC similarity). Dimeric MAD2L1 in the closed conformation interacts with
CC CDC20 (By similarity). Monomeric MAD2L1 in the open conformation does
CC not interact with CDC20 (By similarity). CDC20 competes with MAD1L1 for
CC MAD2L1 binding (By similarity). In the closed conformation, interacts
CC with BUB1B (By similarity). Interacts with TTK (By similarity).
CC Interacts with TPR (By similarity). Binds to UBD (via ubiquitin-like 1
CC domain) during mitosis (By similarity). Interacts with isoform 1 and
CC isoform 2 of NEK2 (By similarity). Interacts with HSF1; this
CC interaction occurs in mitosis (By similarity).

CC {ECO:0000250}. Note=Recruited by MAD1L1 to unattached kinetochores (By
CC similarity). Recruited to the nuclear pore complex by TPR during
CC interphase (By similarity). Recruited to kinetochores in late
CC prometaphase after BUB1, CENPF, BUB1B and CENPE. Kinetochore
CC association requires the presence of NEK2 (By similarity).
CC {ECO:0000250}.
CC -!- DOMAIN: The protein has two highly different native conformations, an
CC inactive open conformation that cannot bind CDC20 and that predominates
CC in cytosolic monomers, and an active closed conformation. The protein
CC in the closed conformation preferentially dimerizes with another
CC molecule in the open conformation, but can also form a dimer with a
CC molecule in the closed conformation. Formation of a heterotetrameric
CC core complex containing two molecules of MAD1L1 and of MAD2L1 in the
CC closed conformation promotes binding of another molecule of MAD2L1 in
CC the open conformation and the conversion of the open to the closed
CC form, and thereby promotes interaction with CDC20 (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Phosphorylated on multiple serine residues. The level of
CC phosphorylation varies during the cell cycle and is highest during
CC mitosis. Phosphorylation abolishes interaction with MAD1L1 and reduces
CC interaction with CDC20. Phosphorylated by NEK2 (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MAD2 family. {ECO:0000305}.
