Anti-Wilms tumor 1 interacting protein antibodies enable researchers to detect and measure the Wilms tumor 1 interacting protein antigen in biological samples. This target is a reported synonym of the WTIP gene, which encodes WT1 interacting protein. This protein is known to function in cytoskeleton organization and the regulation of transcription, among other biological roles. The human version of Wilms tumor 1 interacting protein has a canonical amino acid length of 430 residues and a protein mass of 45.1 kilodaltons. It is reported to be localized in the nucleus, cell junctions, and cytoplasm of cells. Other names for this target antigen include Wilms tumor protein 1-interacting protein and Wilms tumor 1 interacting protein.
