Protein attributes
| Sequence length | 8545 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays a central role in nuclear and mitochondrial anchoring. Probably connects nuclei to the cytoskeleton by interacting with unc-84 at the nuclear envelope and with F-actin in the cytoplasm, creating a bridge across the nuclear envelope between the cytoskeleton and the nucleus. Ref.1 |
| Subunit structure | Interacts with F-actin via its N-terminal domain. Interacts indirecty with unc-84. Ref.1 |
| Subcellular location | Nucleus outer membrane; Single-pass type IV membrane protein; Cytoplasmic side Potential. Cytoplasm › cytoskeleton. Note: The largest part of the protein is cytoplasmic, while its C-terminal part is associated either with the nuclear envelope, most probably the outer nuclear membrane, or with mitochondrial membrane. |
| Tissue specificity | Ubiquitously expressed in all postembryonic cells. |
| Developmental stage | First expressed in L1 larvae, and thereafter. |
| Domain | The large coiled coil domains are composed of 6 nearly exact repeats of 903 residues. The last repeat is partial. These repeats are conserved in Hawai (CB4856), Australia (AB4) and Germany (RC301) strains. The length of the repeat may be maintained because of a selective advantage to keep the protein large and allow a single molecule to extent more than 0,5 micrometers. The KASH domain, which contains a potential transmembrane domain, is essential for the nuclear envelope targeting. |
| Sequence similarities | Belongs to the nesprin family. Contains 1 actin-binding domain. Contains 2 CH (calponin-homology) domains. Contains 1 KASH domain. |
