Gene: SUN2 (Sad1 and UNC84 domain containing 2) Homo sapiens
Symbol: SUN2
Name: Sad1 and UNC84 domain containing 2
Description: Exhibits cytoskeleton-nuclear membrane anchor activity; identical protein binding activity; and lamin binding activity. Involved in nuclear envelope organization and nuclear matrix anchoring at nuclear membrane. Localizes to meiotic nuclear membrane microtubule tethering complex and nuclear membrane.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: KIAA0668; MGC133055; MGC133056; nuclear envelope protein; rab5-interacting protein; rab5IP; Sad1 unc-84 domain protein 2; sad1/unc-84 protein-like 2; SUN domain-containing protein 2; unc-84 homolog B; UNC84B
