Andere Bezeichnung: CCL19

Hintergrund: CCL19 is a CC chemokine expressed in lymph nodes. CCL19 is only 32 % identical to CCL21 at the amino acid level, nevertheless, these chemokines bind to the same receptor: CCR7. CCL19 is not expressed in high endothelial venules (HEV) as CCL21, but CCL19 is transcytosed in HEV. It has been described that CCL19 binds to CCX-CKR and CRAM-B receptors. These two receptors are members of the non classical chemokine receptor family which, in addition, includes D6, DARC, and CXCR7. CCX-CKR has been suggested to be a scavenging receptor for CCL19, and CRAM-B receptor might be responsible for the transcytosis in HEV for CCL19. In addition, CRAM recycles constitutively, and can internalize CCL19 within a few minutes, suggesting an implication in the regulation of immune responses and homing processes.

Molekulargewicht: The 84 amino acid recombinant protein has a predicted molecular mass of approximately 9.3 kDa. The DTT-reduced and non-reduced protein migrate from 12-20 kDa by SDS-PAGE. The N-terminal amino acid is Gly.
