Anti-MUM2 antibodies are used in antigen-specific immunodetection in biological samples. The target MUM2 is a known alias name of the protein WT1 associated protein, encoded by the WTAP gene in humans. This 396-amino acid residue protein is reported to be an associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of RNAs, a modification that plays a role in the efficiency of mRNA splicing and RNA processing. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue expression, it is ubiquitously expressed across many tissue types.
