The KASH (for Klarsicht/ANC-1/Syne-1 homology) or KLS domain is a highly hydrophobic nuclear envelope localization domain of ~60 amino acids comprising an ~20-amino-acid transmembrane region and a 30-35-residue C-terminal region that lies between the inner and the outer nuclear membranes. The KASH domain is found in association with other domains, such as spectrin repeats and CH (see <PDOC50021>), at the C-terminus of proteins tethered to the nuclear membrane in diverse cell types [1,2,3,4,5].
Some proteins known to contain a KASH domain are listed below:
- Caenorhabditis elegans nuclear anchorage protein 1 (ANC-1).
- Drosophila Klarsicht (Klar), a protein associated with nuclei and required for a subset of nuclear migrations.
- Drosophila MSP-300.
- Vetebrate nesprin-1 and -2 (also known as Syne-1 and -2). They are associated with emerin and lamin A at the nuclear envelope of muscle cells and other cell types.
The profile we developed covers the entire KASH domain.
