Identification of an enzymatic activity required for the completion of cell division
Cell division, a process required for the survival of all species, enables the genetic material of a mother cell to be separated and shared between its two daughter cells. As many aspects of cell division remain poorly understood, the team led by Jean-Claude Labbé, Director of the Cell Division and Differentiation Research Unit, focused on one of its final stages, cytokinesis. The team identified a new protein, OSGN-1, as being required for the correct completion of cell division. The study, published in the journal PNAS, was led by research associate Eugénie Goupil and doctoral student Léa Lacroix.
