Anti-Nucleoporin 133kD antibodies enable researchers to detect and measure the Nucleoporin 133kD antigen in biological samples. This target is a reported synonym of the NUP133 gene, which encodes nucleoporin 133. This protein is known to be involved in poly(A)+ RNA transport. The human version of Nucleoporin 133kD has a canonical amino acid length of 1156 residues and a protein mass of 129 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Nucleoporin 133kD is a member of the Nucleoporin Nup133 protein family.
