MIP-5 is a CC chemokine that is expressed in the heart, skeletal muscle and adrenal gland. MIP-5 primarily signals through he CCR1 receptor, but also has been found to bind to CCR3. MIP-5 is chemotactic towards T cells and monocytes. Recombinant human MIP-5 is a 10.1 kDa protein containing 92 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.
