TAFA4/FAM19A4 Proteins and Enzymes

TAFA4 (also FAM19A4) is a secreted, 12 kDa member of the FAM19/TAFA family of chemokine-like proteins (1). It is synthesized as a 140 amino acid (aa) precursor that contains a 35 aa signal sequence and a 105 aa mature chain (SwissProt #: Q8N3H0). Like other members of the FAM19/TAFA family, with the exception of TAFA5, mature TAFA1 contains 10 regularly spaced cysteine residues that follow the pattern CX₇CCX₁₃CXCX₁₄CX₁₁CX₄CX₅CX₁₀C, where C represents a conserved cysteine residue and X ...
