Target Background | Chemokine (C-C motif) ligand 21 (CCL21) is a small cytokine belonging to the CC chemokine family. This chemokine is also known as 6Ckine, exodus-2, and secondary lymphoid-tissue chemokine (SLC). CCL21 contains four conserved cysteines characteristic of β chemokines plus two additional cysteines in an unusually long carboxyl-terminal domain. It is expressed in lymphatic endothelial cells and the spleen. CCL21 chemoattracts T and B lymphocytes and inhibits hematopoiesis. It can signal through the CCR7 receptor. |
Name | PPBP |

Synonyms | CTAP3, CXCL7, SCYB7, TGB1, THBGB1 |
Function | LA-PF4 stimulates DNA synthesis, mitosis, glycolysis, intracellular cAMP accumulation, prostaglandin E2 secretion, and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by human synovial cells. NAP-2 is a ligand for CXCR1 and CXCR2, and NAP-2, NAP-2(73), NAP-2(74), NAP-2(1-66), and most potent NAP-2(1-63) are chemoattractants and activators for neutrophils. TC-1 and TC-2 are antibacterial proteins, in vitro released from activated platelet alpha-granules. CTAP-III(1-81) is more potent than CTAP-III desensitize chemokine-induced neutrophil activation. |
Cellular Location | Secreted. |
