ID:CDCA5_HUMAN DESCRIPTION: RecName: Full=Sororin; AltName: Full=Cell division cycle-associated protein 5; AltName: Full=p35; FUNCTION: Regulator of sister chromatid cohesion in mitosis stabilizing cohesin complex association with chromatin. May antagonize the action of WAPAL which stimulates cohesin dissociation from chromatin. Cohesion ensures that chromosome partitioning is accurate in both meiotic and mitotic cells and plays an important role in DNA repair. Required for efficient DNA double-stranded break repair. SUBUNIT: Interacts with the APC/C complex (By similarity). Interacts with the chromatin-bound cohesin complex; the interaction is indirect, occurs after DNA replication and requires acetylation of the cohesin component SMC3. Interacts (via the FGF motif) with PDS5A and PDS5B; the interaction is direct and prevents the interaction of PDS5A with WAPAL. INTERACTION: Q29RF7:PDS5A; NbExp=2; IntAct=EBI-718805, EBI-1175454; SUBCELLULAR LOCATION: Nucleus. Chromosome. Cytoplasm. Note=Associates with nuclear chromatin from S phase until metaphase and is released in the cytoplasm upon nuclear envelope breakdown. DOMAIN: The KEN box is required for the association with the APC/C complex (By similarity). PTM: Phosphorylated. Phosphorylation, as cells enter mitosis, disrupts the interaction with PDS5A and relieves the inhibition of WAPAL by CDCA5. PTM: Ubiquitinated by the APC/C complex in G1, leading to its degradation (Probable). MISCELLANEOUS: Named sororin after the Latin word 'soror', which means 'sister', because of its critical role in sister chromatid cohesion. SIMILARITY: Belongs to the sororin family.
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.
