Proteins involved in Cytokinesis:
Cytokinesis is the division of the cytoplasm and the plasma membrane following the division of the nucleus resulting into two cells, each having its own nucleus and cytoplasm surrounded by a plasma membrane. This process begins during the late stage of mitosis (Telophase) and meiosis (Telophase II). In animal cells (and in some plant cells) it is marked by a constriction of the cell membrane called the cleavage furrow. In most plant cells it happens when an expanding cell plate forms across the center of the cytoplasm called the phargmoplast.

Reducing the distance from the cortex to the mitotic apparatus (MA) leads to early cytokinesis (Lychechinus pictus).
