quantitation of 99 abundant polypeptides ( acidic and basic ) in pulse-labeled and long-term labeled cells revealed that the relative amount ( i.e. , the rate of synthesis ) of most polypeptides , including total actin , alpha-actinin , 6 abundant basic nonhistone proteins , and 13 major acidic proteins present in triton cytoskeletons , remains constant throughout the cell cycle .
