Chemokine (C-C motif) ligand 3 (CCL3) is a protein that in humans is encoded by the CCL3gene.
CCL3, also known as macrophage inflammatory protein 1α (MIP1α), is a cytokine belonging to the CC chemokine family that is involved in the acute inflammatory state in the recruitment and activation of polymorphonuclear leukocytes (Wolpe et al., 1988). Sherry et al. (1988) demonstrated 2 protein components of MIP1, called by them alpha and beta.
