Description: Homo sapiens MAD2 mitotic arrest deficient-like 2 (yeast) (MAD2L2), transcript variant 2, mRNA. RefSeq Summary (NM_006341): The protein encoded by this gene 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. The encoded protein, which is similar to MAD2L1, is capable of interacting with ADAM9, ADAM15, REV1, and REV3 proteins. [provided by RefSeq, Jul 2008]. Transcript (Including UTRs) Position: hg19 chr1:11,734,537-11,741,495 Size: 6,959 Total Exon Count: 9 Strand: - Coding Region Position: hg19 chr1:11,734,832-11,740,658 Size: 5,827 Coding Exon Count: 8
ID:MD2L2_HUMAN DESCRIPTION: RecName: Full=Mitotic spindle assembly checkpoint protein MAD2B; AltName: Full=Mitotic arrest deficient 2-like protein 2; Short=MAD2-like protein 2; AltName: Full=REV7 homolog; Short=hREV7; FUNCTION: Adapter protein able to interact with different proteins and involved in different biological processes. Mediates the interaction between the error-prone DNA polymerase zeta catalytic subunit REV3L and the inserter polymerase REV1, thereby mediating the second polymerase switching in translesion DNA synthesis. Translesion DNA synthesis releases the replication blockade of replicative polymerases, stalled in presence of DNA lesions. May also regulate another aspect of cellular response to DNA damage through regulation of the JNK-mediated phosphorylation and activation of the transcriptional activator ELK1. Inhibits the FZR1- and probably CDC20-mediated activation of the anaphase promoting complex APC thereby regulating progression through the cell cycle. Regulates TCF7L2-mediated gene transcription and may play a role in epithelial-mesenchymal transdifferentiation. SUBUNIT: Homooligomer (Probable). Interacts with REV1. Interacts with ADAM9. Interacts with CHAMP1. Interacts with REV3L. Interacts with FZR1 (in complex with the anaphase promoting complex APC). Interacts with CDC20; PubMed:11459825 could not detect the interaction. Interacts with RAN. Interacts with ELK1; the interaction is direct and recruits MAD2L2 to ELK1-specific promoters. May interact with the JNK kinases MAPK8 and/or MAPK9 to stimulate ELK1 phosphorylation and transcriptional activity upon DNA damage. Interacts with TCF7L2; prevents its binding to promoters and negatively modulates its transcriptional activity. Interacts with YY1AP1. Interacts with S.flexneri protein ipaB; prevents the interaction of MAD2L2 with FZR1 and CDC20 resulting in an activation of the anaphase-promoting complex APC and a cell cycle arrest. Interacts with PRCC; the interaction is direct. Interacts with POGZ.

Cytoplasm, cytoskeleton, spindle. Cytoplasm. TISSUE SPECIFICITY: Ubiquitously expressed. SIMILARITY: Contains 1 HORMA domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
