The function of KIF2C (kinesin family member 2C, Ensembl gene identifier ENSG00000142945) is as follows. 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). {ECO:0000269|PubMed:19060894, ECO:0000269|PubMed:21820309, ECO:0000269|PubMed:23891108}.
