The MCAK protein also known as KIF2C (kinesin family member 2C) is a motor protein that makes depolymerization of microtubules. It serves an important role in the regulation of microtubule dynamics during mitosis. MCAK has a molecular mass of approximately 81 kDa. Expression of MCAK is mostly found in actively dividing cells such as those in tissues with high turnover rates including the skin intestinal lining and specific tumors. This protein is critical for the proper formation and functioning of the mitotic spindle during cell division.

Biological function summary

The MCAK protein contributes to accurate chromosome segregation. MCAK performs its functions by binding to microtubule ends and removing tubulin subunits thereby aiding in microtubule disassembly. It functions within the mitotic spindle apparatus and ensures that chromosomes align properly and evenly separate to opposite poles of the dividing cell. This activity is not part of a complex but acts independently to correct improper microtubule attachments.

Pathways

MCAK plays a significant role in mitotic and cell cycle pathways. It coordinates with other proteins like Aurora B kinase which is involved in correcting improper kinetochore-microtubule attachments to maintain chromosome stability during mitosis. MCAK interacts with proteins controlling cell cycle checkpoints overlapping with pathways ensuring cells do not progress with errors in chromosome segregation.

Aberrant regulation of the MCAK protein can lead to chromosomal instability often observed in cancers such as colorectal and breast cancer. This instability can drive tumorigenesis where loss of proper chromosome segregation leads to aneuploidy and cancer progression. In these cancers MCAK may interact with other proteins such as Aurora kinases revealing potential therapeutic targets for intervention in malignancies with defective mitotic processes.
