Nuclear Portals and Calcium requirement therefore

A recent Science had a paper on inside-nucleus construction of cell
components with the details of "portal" formation on the nuclear membrane.
However, one requirement was protoplasmic
calcium ions at a certain level before the portals would open.
My question is: Does anyone remember or know the level of calcium required
That is, are medium-to-low "normal" calcium levels adequate for this?
What are the implications for cell life-span at the threshold level if RNA
and cell components are not allowed to exit the nucleus.... ie
mitochondrial components are 80-85% manufactured by instructions from the
nucleus and some of these proteins turn over every few hours. ?
Interesting stuff, eh?
