MIP-3 alpha (CCL20)

MIP-3α is a CC chemokine that is expressed in the liver, lymph nodes, appendix, PBL and lung and signals through the CCR6 receptor. MIP-3α is chemotactic towards lymphocytes and dendritic cells. Additionally, it promotes the adhesion of memory CD4+ T cells and inhibits colony formation of bone marrow myeloid immature progenitors. Recombinant mouse MIP-3α is a 7.9 kDa protein containing 70 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.
