Predicted Molecular Mass:7.9 kDa Activity:Measured by its ability to chemoattract CEM‑NKr human natural killer cell resistant T-lymphoblastoid cells. Howell,D.N. etal. (1985) J.Immunol. 134:971.The ED₅₀ for this effect is typically 2 - 10 ng/mL.Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CCR4.The ED₅₀ for this effect is typically 2-8ng/mL. Molecule Information: CCL17/TARC Aliases: TARC Entrez Gene IDs: 6361 (Human); 20295 (Mouse) Background: CCL17/TARC (Thymus and Activation Regulated Chemokine) Thymus and activation-regulated chemokine (TARC) is a novel CC chemokine identified using a signal sequence trap method. Among CC chemokine family members, TARC has approximately 24 - 29% amino acid sequence identity with RANTES, MIP-1 alpha, MIP-1 beta, MCP-1, MCP-2, MCP-3 and I-309. TARC is constitutively expressed in thymus, and at a lower level in lung, colon, and small intestine.
