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.
May be involved in cooperative interactions with calmodulins or calmodulin-like proteins (By similarity). Recruits calmodulin proteins to microtubules, thus being a potential scaffold in cellular signaling and trafficking (By similarity). May associate with nucleic acids and regulate gene expression at the transcriptional or post- transcriptional level (By similarity). {By
