What's inside the perinuclear space?

Question

The cell proper contains the cytoplasm in general and the cytosol in particular when referring to the fluid/gel without notable organelle.Once we move inside the nucleus there is the nucleoplasm and the nucleosol.My question is in the intervening void of the perinuclear space (between the inner and outer membrane of the nuclear envelope) what if any is the terminology used to refer to the internal chemistry in that space - and what is known about it's makeup?

Answer 1

A Nature article examines this very question. To quickly summarize the article, scientists believe there are several protein complexes occuring in the perinuclear space but they only have a vague idea of what complexes. I will let you review the article in a link that will be in the comments.
