Activity summary

Nesprin-3 also known as SYNE3 is a mechanical adaptor protein of around 215 kDa. It belongs to the spectrin repeat family and is primarily expressed in the outer nuclear membrane. This protein anchors the nucleus to the cytoskeleton by interacting with cytoskeletal linkers like plectin. It plays a role in maintaining the structural integrity of the nucleus and cellular architecture due to these anchoring functions.

Biological function summary

Nesprin-3 is involved in the linking of the nuclear envelope to the cytoskeleton and it forms part of the LINC (Linker of Nucleoskeleton and Cytoskeleton) complex. This complex is important for nuclear movement within cells and has a role in signal transduction from the cell surface to the nucleus. Through its ability to bind to other cytoskeletal elements Nesprin-3 contributes to force transmission across the cell impacting cell polarity and migration.

Pathways

Nesprin-3 interacts with several cytoskeletal signaling pathways particularly the actin and intermediate filament pathways. It associates with proteins like plectin and vimentin playing significant parts in cellular mechanics and signaling. By engaging in these pathways Nesprin-3 helps control cellular responses to mechanical stress and influences various processes including cell migration and division.

Associated diseases and disorders

Nesprin-3 has been linked to muscular dystrophies and certain cancers. In muscular dystrophies its interactions with plectin can become disrupted leading to compromised muscle integrity and function. In cancer changes in its expression or interactions may affect cell movement and invasion contributing to metastasis. Its role in these diseases highlights its importance in maintaining proper cell architecture and function.
