    text
  • REV3L and MAD2L2 show an unexpected increase in expression during G(2)/M phase, but they localize independently in mitotic cells
  • basic FUNCTION
  • preventing the onset of anaphase until all chromosomes are properly aligned at the metaphase plate
  • has a widespread role in coordinating the cellular response to DNA damage (Zhang 2007)
  • involved in TCF7L2-mediated epithelial-mesenchymal transdifferentiation (Hong 2009)
  • blocks TCF7L2-mediated transactivation (interactions abolished the DNA binding ability of TCF7L2)(Hong 2009)
  • REV1, REV3L and MAD2L2 play important roles in translesion DNA synthesis (TLS) in which DNA replication bypasses blocking lesions (pMID: 21926160)
  • MAD2L2 may mediate SIM2 function during development in CNS and thereby play a critical role in pathophysiological mechanisms in Down syndrome
  • REV1, REV3L, and MAD2L2 are pivotal proteins in translesion DNA synthesis, which allows DNA synthesis even in the presence of DNA damage
  • function of MAD2L2 is essential in primordial germ cells (PGCs), and thus of high relevance for fertility
  • is indispensible for mitotic checkpoint control and DNA repair
  • role in the FA-BRCA pathway and DNA interstrand crosslink (ICL) repair
  • is a necessary downstream effector of the FA-BRCA pathway, most likely functioning in the translesion DNA synthesis step of ICL repair
  • important epigenetic function of MAD2L2, a protein originally known for its role in DNA damage repair, and for its requirement in germ cell development
  • important function of MAD2L2 for the open chromatin configuration of ESCs
  • CELLULAR PROCESS cell cycle, division, mitosis
    cell cycle, checkpoint
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • component of the mitotic spindle assembly checkpoint
  • key component of a surveillance system that delays anaphase until all chromosomes are correctly oriented (Rimkus 2007)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • associating with the anaphase promoting complex (APC), thereby inhibiting its ubiquitin ligase activity
  • REV3, ADAM9 (MDC9)
  • interaction partner for ELK1 (MAD2L2 acts to promote ELK1 phosphorylation by the c-Jun N-terminal protein kinase (JNK) MAP kinases) (Zhang 2007)
  • YY1AP1-interacting protein, is MAD2L2
  • interacts with TCF7L2 (is a TCF7L2-binding protein, and interaction abolished the DNA binding ability of TCF7L2) (Hong 2009)
  • RAN is a novel MAD2L2 binding protein (protein-protein interaction may play a role in the control over the spindle checkpoint during mitosis andin the regulation of nucleocytoplasmic trafficking during interphase
  • modulates expression of SNAI2, a TCF4-beta-catenin-inducible gene, and E-cadherin, a downstream target gene of SNAI2 (Hong 2009)
  • interacts with CLTA during the G2/M phase of the cell cycle and depletion of MAD2l2 leads to a marked increase in the percentage of misaligned chromosomes and a redistribution of CLTA during mitosis (pMID: 21152103)
  • MAD2L2 is a novel SIM2 binding protein
  • role of MAD2L2 in governing REV1 stability and interplay between translesion DNA synthesis (TLS) and anaphase-promoting complex (APC)-dependent proteolysis
  • MAD2L2 helps to ensure a robustly bistable switch between APC/C(CDC20) and APC/C(CDH1) during the metaphase-to-anaphase transition, thereby contributing to mitotic fidelity
  • MAD2L2 has a profibrotic role during fibroblast activation and tubulointerstitial fibrosis (TIF) by suppressing SKIL expression
  • stabilize and enhance the polymerase activity of the catalytic subunit, REV3L
  • MAD2L2 promotes open chromatin in embryonic stem cells and derepresses the DPPA3 Locus
