ID:INCE_HUMAN DESCRIPTION: RecName: Full=Inner centromere protein; FUNCTION: Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Probably acts through association with AURKB or AURKC. Seems to bind directly to microtubules. Controls the kinetochore localization of BUB1. SUBUNIT: Homodimer or heterodimer. Interacts with H2AFZ (By similarity). Interacts with CBX3. Interacts with tubulin beta chain. Interacts with AURKB and AURKC. Component of the chromosomal passenger complex (CPC) composed of at least BIRC5/survivin, CDCA8/borealin, INCENP, AURKB and AURKC. Interacts with EVI5. Interacts with CDCA8 and BIRC5; interaction is direct. Interacts with CBX5; POGZ and INCENP compete for interaction with CBX5. Interacts with POGZ. Interacts with JTB. INTERACTION: Q96GD4:AURKB; NbExp=3; IntAct=EBI-307907, EBI-624291; P45973:CBX5; NbExp=6; IntAct=EBI-307907, EBI-78219; Q53HL2:CDCA8; NbExp=4; IntAct=EBI-307907, EBI-979174; SUBCELLULAR LOCATION: Chromosome, centromere. Cytoplasm, cytoskeleton, spindle. Nucleus. Chromosome, centromere, kinetochore. Note=Localizes to inner kinetochore. Localizes on chromosome arms and inner centromeres from prophase through metaphase and then transferring to the spindle midzone and midbody from anaphase through cytokinesis. Colocalizes with AURKB at mitotic chromosomes. PTM: Phosphorylation by AURKB at its C-terminal part is important for AURKB activation by INCENP. SIMILARITY: Belongs to the INCENP family. CAUTION: PubMed:11139336 experiments have been carried out partly in chicken and partly in human.
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.
