The nuclear envelope is a membrane system which surrounds the nucleoplasm of eukaryotic cells. It is composed of the nuclear lamina, nuclear pore complexes and two nuclear membranes. The space between the two membranes is called the nuclear intermembrane space.
Part of a complex with bicd-1 and dlc-1, which is recruited to the nuclear envelope by unc-83, where in turn, it recruits dynein to the nuclear surface and regulates nuclear migration in hypodermal precursor cells. {Experimental EvidencePubMed:20005871}.
