Anti-mago homolog B, exon junction complex core component antibodies enable researchers to detect and measure the mago homolog B, exon junction complex core component antigen in biological samples. This target is a reported synonym of the MAGOHB gene, which encodes mago homolog B, exon junction complex subunit. This protein is known to function in RNA splicing, among other biological roles. The human version of mago homolog B, exon junction complex core component has a canonical amino acid length of 148 residues and a protein mass of 17.3 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include MGN2, mago, and magoh.
