Anti-TAFA chemokine like family member 4 antibodies are used for the immunodetection of the protein encoded by the TAFA4 gene. In humans, the canonical protein has a reported length of 140 amino acid residues and a mass of 15.7 kDa. It is known to be a secreted protein. It is notably expressed in the brain. It is a member of the TAFA protein family. Other names for this target antigen include family with sequence similarity 19 (chemokine (C-C motif)-like), member A4, family with sequence similarity 19 member A4, C-C motif chemokine like, protein FAM19A4, and chemokine-like protein TAFA-4. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
