Anti-RAE1 antibodies are used in the immunodetection of the protein ribonucleic acid export 1. In humans, the canonical protein has a reported length of 368 amino acid residues and a mass of 41 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of a the WD repeat rae1 protein family, RAE1 is known to act as mRNA export factor involved in nucleocytoplasmic transport. Synonyms for this target antigen include MIG14, MRNP41, Mnrp41, dJ481F12.3, dJ800J21.1, mRNA export factor RAE1, RAE1 RNA export 1 homolog, and Gle2.
