Anti-NXF3 antibodies are used in the immunodetection of the protein nuclear RNA export factor 3. In humans, the canonical protein has a reported length of 531 amino acid residues and a mass of 60.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is notably expressed at high level in testis and at low level in a small number of tissues. A member of a the NXF protein family, NXF3 is believed to function as a a tissue-specific nuclear mRNA export factor. Synonyms for this target antigen include TAP-like protein 3 and TAPL-3.
