Anti-LILRA5 antibodies are used in the immunodetection of the protein leukocyte immunoglobulin like receptor A5. In humans, the canonical protein has a reported length of 299 amino acid residues and a mass of 32.8 kDa. Its subcellular localization is in the cell membrane and is secreted. Up to 4 different isoforms have been reported for this protein. It is noted to be expressed mostly in tissues of the hematopoietic system, including bone marrow, spleen, lymph node and peripheral leukocytes. LILRA5 is believed to play a role in triggering innate immune responses. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include CD85 antigen-like family member F, immunoglobulin-like transcript 11 protein, leucocyte Ig-like receptor A5, leukocyte Ig-like receptor 9, and leukocyte immunoglobulin-like receptor subfamily A member 5. LILRA5 gene orthologs have been reported in the mouse and rat species.
