Recombinant CCL27 (CTACK)
Catalog No., Size:
CCL27, also known as Cutaneous T-cell-attracting Chemokine (CTACK) is a ligand for cell surface receptor CCR10. It is responsible for chemotaxis of skin-homing memory T-cells during cutaneous inflammation. Interestingly, after CCR10-mediated internalization, CCL27, as well as a non-secreted splice variant of the same gene, can reach the nucleus and modulate transcription and cell behavior.
Source: Recombinant human CCL27, produced in E. coli, corresponds to aa 25- 112 (accession no. Q9Y4X3).
