| Cellular localization: |
[Isoform 2]: Nucleus inner membrane ; Multi-pass membrane protein . Cytoplasm, cytoskeleton, spindle pole . The C-terminal of isoform 2 is located on the nucleoplasmic side. During interphase, isoform 2 is distributed in the inner nuclear membrane in distinct micro-domains and during mitosis, it is found in the ER but it also localizes to the polar regions of the mitotic spindle. . |
