General description

MIP-3 α, also known as LARC or Exodus, is one of the many chemokines identified through the Expressed Sequence Tag database. MIP-3 alpha, cDNA encodes a 96 amino acid precursor protein and a 26 amino acid signal peptide. The resulting 70 amino acid mature protein has only 20-28% homology with other related human chemokines. The gene for MIP-3 alpha has been mapped to chromosome 2 rather than chromosome 17 where many human chemokine genes are located. Expression of the chemokine is detected in the lymphoid tissues, fetal lung and fetal liver. Recombinant and native MIP-3 alpha are known chemoattractants of lymphocytes in vitro. Additionally, a growing body of work has identified MIP-3 alpha as a functional ligand of GPR-CY4 orphan receptor or CCR6 and given useful information about in vivo function.

Biochem/physiol Actions

Analysis Note

The biological activity is measured by its ability to induce calcium flux in HEK293 cells stably expressing CCR-6 and for chemotaxis of mouse BaF/3 cells transfected with hCCR6.

The ingrained capacity of melanoma cells to rapidly evolve toward an aggressive phenotype is manifested by their increased ability to develop drug-resistance, evident in the case of vemurafenib, a therapeutic-agent targeting BRAFV600E. Previous studies indicated a tight correlation between heightened
