Anti-JHDM1B antibodies enable researchers to detect and measure the JHDM1B antigen in biological samples. This target is a reported synonym of the KDM2B gene, which encodes lysine demethylase 2B. This protein is known to function in chromatin remodeling and brain development, among other biological roles. The human version of JHDM1B has a canonical amino acid length of 1336 residues and a protein mass of 152.6 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus of cells. JHDM1B is a member of the JHDM1 histone demethylase protein family.
