Anti-MST107 antibodies are used in antigen-specific immunodetection in biological samples. The target MST107 is a known alias name of the protein WD repeat domain 82, encoded by the WDR82 gene in humans. This 313-amino acid residue protein is a reported regulatory component of the SET1 complex implicated in the tethering of this complex to transcriptional start sites of active genes. It is localized to the nucleus of the cell.
