概述

Chemokine (C-C motif) ligand 1 (CCL1) belongs to a family inflammatory cytokines and also known as chemokines. It is a small glycoprotein secreted by activated T cells with a molecular weight of approximately 8.5 kDa. CCL1 attracts monocytes, NK cells, and immature B cells and dendritic cells by interacting with a cell surface chemokine receptor called CCR8. Human CCL1 has been assumed to be a homologue of the mouse TCA3. While the two proteins share only approximately 42 % amino acid sequence identity, both chemokines contain an extra pair of cysteine residues not found in most other chemokines.
