The plant LINC complex at the nuclear envelope.

摘要: Significant advances in understanding the plant nuclear envelope have been made over past few years; indeed, knowledge of protein network at is rapidly growing. One such network, linker nucleoskeleton and cytoskeleton (LINC) complex, known animals to connect chromatin through envelope. The LINC complex Sad1/Unc84 (SUN) Klarsicht/Anc1/Syne1 homology (KASH) proteins which recently characterized plants. SUN are located within inner membrane, while KASH included into outer membrane. domains interact bridge two membranes. In Arabidopsis, also with tryptophan–proline–proline (WPP) domain-interacting tail-anchored 1 (WIT1), associated pore myosin XI-i directly interacts actin cytoskeleton. Although evidence for a connecting nucleus growing, its interaction still unknown, but gained from animal models strongly suggests existence Possible functions cell division, shape, organization discussed.
