Anti-AIRAPL antibodies enable researchers to detect and measure the AIRAPL antigen in biological samples. This target is a reported synonym of the ZFAND2B gene, which encodes zinc finger AN1-type containing 2B. This protein is reported to play a role in protein homeostasis by regulating both the translocation and the ubiquitin-mediated proteasomal degradation of nascent proteins at the endoplasmic reticulum. The human version of AIRAPL has a canonical amino acid length of 257 residues and a protein mass of 28 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the ER of cells.
