Anti-Nup188 antibodies are used in the immunodetection of the protein nucleoporin 188. In humans, the canonical protein has a reported length of 1749 amino acid residues and a mass of 196 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of a the Nup188 protein family, NUP188 is a known component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope (Probable). Synonyms for this target antigen include SANDSTEF, hNup188, nucleoporin NUP188, nucleoporin 188kDa, nucleoporin NUP188 homolog, and KIAA0169.
