Anti-Nesp4 antibodies enable researchers to detect and measure the Nesp4 antigen in biological samples. This target is a reported synonym of the SYNE4 gene, which encodes spectrin repeat containing nuclear envelope family member 4. The human version of Nesp4 has a canonical amino acid length of 404 residues and a protein mass of 43.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. Nesp4 is a member of the Nesprin protein family.
