MIP-3 beta is a CC chemokine that is expressed in the thymus, lymph nodes and in activated bone marrow stromal cells and signals through the CCR7 receptor. MIP-3 beta is a chemoattractant for T and B lymphocytes and myeloid progenitor cells. Human MIP-3 beta is active on murine cells. Recombinant murine MIP-3 beta is a 9.2kD protein containing 83aa, including the four highly conserved cysteine residues present in CC chemokines.
