Anti-ULBP5 antibodies enable researchers to detect and measure the ULBP5 antigen in biological samples. This target is a reported synonym of the RAET1G gene, which encodes retinoic acid early transcript 1G. This protein is known to function in immune response pathways, among other biological roles. The human version of ULBP5 has a canonical amino acid length of 334 residues and a protein mass of 37.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the ER and cell membrane of cells. ULBP5 is a member of the MHC class I protein family.
