Additional Information
Gene ID 100042493;100504239;100504346;100862177
Other Names C-C motif chemokine 21b, 6Ckine, Beta-chemokine exodus-2, Small-inducible cytokine A21b, Thymus-derived chemotactic agent 4, TCA4, Ccl21b, Scya21, Scya21b
Target Background Exodus-2/CCL21 is a novel CC chemokine discovered independently by three groups from the EST database, and shows 21-33% identity to other CC chemokines. Exodus-2 contains the four conserved cysteines characteristic of β chemokines plus two additional cysteines in its unusually long carboxyl terminal domain. It is expressed in lymph nodes of certain endothelial cells, and in the spleen and appendix. Exodus-2 chemoattracts T and B lymphocytes and inhibits hematopoiesis.
Protein Information
Name Ccl21b
Synonyms Scya21, Scya21b
Function Inhibits hemopoiesis and stimulates chemotaxis. Chemotactic in vitro for thymocytes and activated T-cells, but not for B-cells, macrophages, or neutrophils. Potent mesangial cell chemoattractant. Shows preferential activity towards naive T-cells. May play a role in mediating homing of lymphocytes to secondary lymphoid organs.
Cellular Location Secreted.
Tissue Location Expressed strongly in lung, spleen, thymus, peripheral and mesentric lymph nodes. Also expressed in the testis, kidney, liver, and heart
