Cell biology: Lost in mitotic translation
Anthony Wynshaw-Boris1
Abstract
A protein called 14-3-3
inhibits the cell cycle and may act as a tumour suppressor. It now turns out that it is also involved in regulating protein synthesis from messenger RNA during cell division.
Movement through the cell cycle is regulated by structural modification of proteins after they have been translated from messenger RNA (mRNA). Such changes are known to be important in regulating DNA checkpoint and repair pathways, in triggering cell division (mitosis) and in maintaining the mitotic spindle, which ensures that the chromosomes separate correctly.
