Model confidence (pLDDT)

The mean pLDDT of this model is 76.7 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of chromosome segregation and cytokinesis (PubMed:11853667, PubMed:12408861). Has a role in error-correction of aberrent kinetochore-microtubule attachments to ensure that sister kinetochores become bioriented and connect to opposite poles by promoting spindle assembly checkpoint signaling (PubMed:11724818, PubMed:11853667, PubMed:12408861). Acts in opposition to the phosphatase PP1 (PubMed:10975519). Not required for kinetochore detachment from microtubules during replication of centromeric DNA (PubMed:18079178). Phosphorylates histone H3 to form H3S10ph during mitosis and meiosis…

Subunit structure

Component of the CPC complex at least composed of IPL1, BIR1 and SLI15

Subcellular location

Nucleus, Cytoplasm, cytoskeleton, spindle, Chromosome, centromere, kinetochore

Experimental structures

UniProt lists no experimental PDB structure for this protein, so the AlphaFold prediction is the main 3D model available.
