What pLDDT means and how to read it

Function

In complex with KIF18B, constitutes the major microtubule plus-end depolymerizing activity in mitotic cells (PubMed:21820309). Regulates the turnover of microtubules at the kinetochore and functions in chromosome segregation during mitosis (PubMed:19060894). Plays a role in chromosome congression and is required for the lateral to end-on conversion of the chromosome-microtubule attachment (PubMed:23891108)

Subunit structure

Interacts with CENPH. Interacts with MTUS2/TIP150; the interaction is direct. Interacts with MAPRE1; the interaction is direct, regulated by phosphorylation and is probably required for targeting to growing microtubule plus ends. Interacts with KIF18B at microtubule tips; this interaction increases the affinity of both partners for microtubule plus ends and is required for robust microtubule…
