Anti-TAFA chemokine like family member 3 antibodies are used for the immunodetection of the protein encoded by the TAFA3 gene. In humans, the canonical protein has a reported length of 133 amino acid residues and a mass of 14.8 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to have brain-specific expression. A member of the TAFA protein family, it is reported to play a role in the regulation of microglia polarization. Other names for this target antigen include family with sequence similarity 19 (chemokine (C-C motif)-like), member A3, family with sequence similarity 19 member A3, C-C motif chemokine like, protein FAM19A3, and chemokine-like protein TAFA-3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
