Meeting report – Nuclear and cytoplasmic molecular machines at work

ABSTRACT This report summarizes an international conference on molecular machines convened at New York University, Abu Dhabi by Piergiorgio Percipalle, George Shubeita and Serdal Kirmizialtin. The meeting was conceived around the epistemological question of what do we understand, or not understand (if we have open minds), about the degree to which cells operate by the individual actions of single enzymes or non-catalytic protein effectors, versus combinations of these in which their heterotypic association creates an entity that is more finely tuned and efficient – a machine. This theme was explored through a vivid series of talks, summarizing the latest findings on macromolecular complexes that operate in the nucleus or cytoplasm.
