Anti-L3MBTL4 histone methyl-lysine binding protein antibodies enable researchers to detect and measure the L3MBTL4 histone methyl-lysine binding protein antigen in biological samples. This target is a reported synonym of the L3MBTL4 gene, which encodes L3MBTL histone methyl-lysine binding protein 4. This protein is known to function in chromatin organization and the regulation of transcription, among other biological roles. The human version of L3MBTL4 histone methyl-lysine binding protein has a canonical amino acid length of 623 residues and a protein mass of 71.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the bronchus, urinary bladder, and adrenal gland.
