Anti-DIP2 antibodies enable researchers to detect and measure the DIP2 antigen in biological samples. This target is a reported synonym of the WDR3 gene, which encodes WD repeat domain 3. This protein is known to be a part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. The human version of DIP2 has a canonical amino acid length of 943 residues and a protein mass of 106.1 kilodaltons. It is reported to be localized in the nucleus of cells. DIP2 is a member of the WD repeat WDR3/UTP12 protein family.
