SYNE2 (Spectrin Repeat Containing Nuclear Envelope Protein 2), also known as Nesprin-2. is a multi-domain protein critical for maintaining nuclear architecture and mechanical stability in eukaryotic cells. It belongs to the nesprin family, characterized by spectrin-repeat motifs that mediate interactions with cytoskeletal components. SYNE2 anchors the nucleus to the actin cytoskeleton by binding to the linker of nucleoskeleton and cytoskeleton (LINC) complex via its C-terminal KASH domain. This interaction facilitates force transmission between the nucleus and cytoplasm, influencing cellular processes like migration, mechanotransduction, and nuclear positioning during cell division.
The recombinant human SYNE2 protein is typically engineered for functional studies, produced using expression systems like mammalian or insect cells to ensure proper post-translational modifications. Its applications span investigating nuclear envelope pathologies (e.g., muscular dystrophies or cardiomyopathies), exploring roles in cancer cell invasion, and modeling nuclear deformability in mechanically stressed tissues. Mutations in SYNE2 have been linked to Emery-Dreifuss muscular dystrophy and autosomal recessive cerebellar ataxia, making recombinant forms valuable tools for mechanistic research and therapeutic screening. Structural studies of purified domains (e.g., spectrin repeats or KASH) further clarify its interactions with partners like SUN proteins and emerin.
