Kinesin-like protein KIF2C

Gene

Kif2c

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

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

  • Cytoplasmcytoskeleton By similarity
  • Nucleus By similarity
  • Chromosomecentromere By similarity
  • Chromosomecentromerekinetochore By similarity

  • Note: Associates with the microtubule network at the growing distal tip (the plus-end) of microtubules, probably through interaction with MTUS2/TIP150 and MAPRE1. Association with microtubule plus ends is also mediated by interaction with KIF18B. Centromeric localization requires the presence of BUB1 and SGO2.By similarity

Expressioni

Tissue specificityi

Testis. Localized to the meiotically active cells of the seminiferous epithelia in the testis.

Interactioni

Subunit structurei

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 depolymerization. Phosphorylation by AURKA or AURKB strongly reduces KIF18B-binding.By similarity
