Chemokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes.

Furthermore, the binding causes the receptor to be taken inside the cell by endocytosis, to eventually be reprocessed and re-expressed.

[2] The human genome reference assembly contains two full copies of the gene (CCL3L1 and CCL3L3) and an additional partial duplication, which is thought to result in a pseudogene, designated CCL3L2.

This leads to slower advancement of disease in HIV-infected individuals, giving those with greater copy number more resistance.
