Ready-to-use ELISA kits are available for the detection of high-mobility group nucleosome binding domain 5, an alias of the protein, high mobility group nucleosome binding domain 5. The official gene symbol is HMGN5. The protein, with a mass of 31.5 kDa and length of 282 residues, is reported to be nuclear. It is a member of the HMGN family and may be known by other names, including: NBP-45, nucleosome-binding protein 1, nucleosomal binding protein 1, and high mobility group nucleosome-binding domain-containing protein 5.
