TAFA-2 also named FAM19A2 belongs to the TAFA family of chemokine­like proteins. Like other members of the FAM19/TAFA family, with the exception of TAFA5, mature TAFA1 to 4 contain 10 regularly spaced cysteine residues. Human TAFA2 is 97% aa identical to mouse TAFA2. TAFA2 expression can be detected in the central nervous system (CNS), colon, heart, lung, spleen, kidney, and thymus, but its expression in the CNS is 50­ to 1000­fold higher than in other tissues. Within the CNS, TAFA2 expression is highest in the occipital and frontal cortex (3­ to 10­fold more abundantly expressed than in other cortical regions) and medulla. The biological functions of TAFA family members remain to be determined, but there are a few tentative hypotheses.
