Recombinant human UNC84A protein, also known as SUN1 (Sad1/UNC-84 domain-containing protein 1), is a key component of the nuclear envelope that bridges the nucleoskeleton and cytoskeleton. It belongs to the SUN domain protein family, characterized by a conserved C-terminal SUN domain that interacts with KASH domain-containing proteins (nesprins) to form the LINC (linker of nucleoskeleton and cytoskeleton) complex. This complex mediates mechanical coupling between the nucleus and cytoskeletal elements, facilitating processes like nuclear positioning, mechanotransduction, and genome organization.
UNC84A is integral to nuclear envelope architecture and cell migration. Studies link its dysfunction to laminopathies, muscular dystrophy, and progeria-like syndromes due to disrupted nuclear-cytoskeletal interactions. Recombinant UNC84A is produced via genetic engineering, often in expression systems like E. coli or mammalian cells, enabling structural-functional studies. Researchers use it to explore its role in maintaining nuclear integrity, chromatin dynamics, and cellular responses to mechanical stress. Its involvement in meiosis, where it mediates telomere attachment to the nuclear envelope, further highlights its biological significance. Current applications span disease modeling, drug screening, and gene therapy research.
