Anti-TAFA chemokine like family member 2 antibodies are used for the immunodetection of the protein encoded by the TAFA2 gene. In humans, the canonical protein has a reported length of 131 amino acid residues and a mass of 14.6 kDa. Its subcellular localization is in the nucleus and cytoplasm. 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 known to have a role as neurotrophic factor involved in neuronal survival and neurobiological functions. Other names for this target antigen include family with sequence similarity 19 (chemokine (C-C motif)-like), member A2, family with sequence similarity 19 member A2, C-C motif chemokine like, protein FAM19A2, and chemokine-like protein TAFA-2. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
