== Function ==
[https://www.uniprot.org/uniprot/CCL20_HUMAN CCL20_HUMAN] Chemotactic factor that attracts lymphocytes and, slightly, neutrophils, but not monocytes. Inhibits proliferation of myeloid progenitors in colony formation assays. May be involved in formation and function of the mucosal lymphoid tissues by attracting lymphocytes and dendritic cells towards epithelial cells. C-terminal processed forms have been shown to be equally chemotactically active for leukocytes. Possesses antibacterial activity E.coli ATCC 25922 and S.aureus ATCC 29213.<ref>PMID:12149255</ref>

== Publication Abstract from PubMed ==
The structure of the human macrophage inflammatory protein-3alpha (MIP-3alpha) has been determined at 1.81 angstroms resolution by X-ray crystallography. The dimer crystallized in the tetragonal space group I4, with unit-cell parameters a = b = 83.99, c = 57.20 angstroms. The crystals exhibit two molecules in the asymmetric unit. The structure was solved by the molecular-replacement method and the model was refined to a conventional R value of 20.6% (R(free) = 25.7%). MIP-3alpha possesses the same monomeric structure as previously described for other chemokines. However, in addition to limited structural changes in the beta1-beta2 hairpin of monomer B, the electron density is fully defined for a few extra residues at the N- and C-termini of monomer A and the C-terminus of monomer B compared with MIP-3alpha in space group P6(1). As the N-terminal and loop regions have been shown to be critical for receptor binding and signaling, this additional structural information may help in determining the basis of the CCR6 selectivity of MIP-3alpha.
